Since Ghs. 421.78 was deducted from Adjoa's salary pay, her take home pay is Ghs. 4265.46.

Given the following data:

Gross profit can be defined as the profit earned by a business after subtracting its cost of manufacturing and distributing goods from its total revenue (sales).

On a related note, gross salary is the amount of money earned by an individual before any deduction such as tax.

To find how much take home pay Adjoa earned this past month:

[tex]Take\;home = Gross\;salary - deduction\\\\Take\;home = 4687.24 - 421.78[/tex]

Take home = Ghs. 4265.46.

Answer:

methanol because it is liquid at room temperature which means that it melts at a lower temperature

Silicon dioxide is a solid at room temperature and methanol is a liquid. Silicon dioxide has a higher melting point than methanol because silicon dioxide is solid, and with increasing temperature, it will melt.

Melting point is that point or temperature at which the solid items are converted into liquid, and it changes their atoms and the atoms lose their compactness.

Here, two compounds are given, Silicon dioxide and methanol, the first one is solid at room temperature, so it will need more temperature to melt down and methanol is still liquid at room temperature, so its melting point is low.

Thus, methanol is a liquid while silicon dioxide is a solid at ambient temperature. Because silicon dioxide is a solid and melts at greater temperatures, it has a higher melting point than methanol.

Answer:

I would say baking powder maybe or you should try tap water

Answer:

1st one - tap water (ill go over them one by one to help you understand why)

Its honestly rather vinegar or tap water but if I would go with tap water however I could be wrong. I don't take your class lol

Step by step:

First, tap water includes a lot of ions and contaminants. As a result, tap water only contains ions capable of conducting electricity. As a result, tap water is an excellent electrical conductor.

2nd) Ammonia and baking soda are both weak bases. When weak electrolytes dissolve in water, the resulting solution has a low conductivity.

Third, because it releases H+ and CH3COO- ions, the mobility of these ions in the solution assists in electrical conduction. As a result, vinegar is a good electrical conductor.

4th) When dissolved in water, soda compounds (chemicals mostly containing sodium) include ions, and ions assist conduct electricity. As a result, it does not conduct because it lacks ions or charged particles.

Answer:

[tex]\boxed {\boxed {\sf 4.60 \times 10^{23} \ atoms \ Mg}}[/tex]

Explanation:

We are asked to find how many atoms of magnesium are in 0.764 moles of magnesium.

We convert moles to atoms using Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of magnesium. So, there are 6.022 × 10²³ atoms of magnesium in 1 mole of magnesium.

Convert using dimensional analysis and set up a conversion factor using Avogadro's Number.

[tex]\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]

We are converting 0.764 moles of magnesium to atoms, so we multiply by this value.

[tex]0.764 \ mol \ Mg *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]

The units of moles of magnesium cancel.

[tex]0.764 *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 }[/tex]

[tex]0.764 *6.022 \times 10^{23} \ atoms \ Mg[/tex]

[tex]4.600808 \times 10^{23} \ atoms \ Mg[/tex]

The original value of moles (0.764) has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 0 in the thousandth place tells us to leave the 0 in the hundredth place.

[tex]4.60 \times 10^{23} \ atoms \ Mg[/tex]

0.764 moles of magnesium contains approximately 4.60 × 10²³ atoms of magnesium.

Explanation:

The atomic mass of K is 39

from Avogadro's law

39g of K contains 6.02x10^23 atoms

therefore if

39=6.02x19^23

X=5.11×10^22

making X the subject of the formula

X= (5.11×10^22×39)÷6.02×10^23

X= 33g

The statement, that describes grams of potassium (K) contain 5.11 × [tex]10^{22}[/tex] atoms is "33.1 g."

An atom is a fundamental particle of matter that contains at least one proton.

1 mole will be of 6.022 × [tex]10^{23}[/tex] atoms

Then,

[tex]= 5.11*10^{22} \;atoms\;.\;\frac{1\;mol}{6.022*10^{23} \;atoms} \;.\;39.098\;g/mol\\\\= 33.171\;g[/tex]

≈ 33.1 g

As a result, 33.1 g of K contains 5.11 × [tex]10^{22}[/tex] atoms.

Hence, the correct option is 33.1 g.
