How many moles are in a sample of 9.47 x 1024 atoms of argon (Ar)? (Show your calculations for full credit. Correct answers will only receive partial credit.)

Your answer:

Answers

Answer:

15.73 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{9.47 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.730897...[/tex]

We have the final answer as

15.73 moles

Hope this helps you

Answer:

15.7 moles of Ar

Explanation:

Given data:

Number of atoms = 9.47 ×10²⁴ atoms

Number of moles of Ar = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

9.47 ×10²⁴ atoms × 1 mole / 6.022 × 10²³ atoms

1.57×10¹ mol

15.7 mol

What ion would each of the following elements form?
For example, a sodium atom (Na) will form a sodium ion (Na+1). You will need to list the charge of the ion. You will need to list the charge of the ion for the seven questions below.
1. Beryllium (Be)
2. Sulfur (S)
3. Potassium (K)
4. Aluminum (Al)
5. Bromine (Br)
6. Oxygen (O)
7. Magnesium (Mg)

Answers

Answer:

Forming positive ions

Explanation:

A sodium atom has one electron in its outer shell. ... It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1. A positive sign is added to the symbol for sodium, Na +.

0.45 g of hydrated sodium carbonate crystals were heated until 3.87 of anhydrous power remained.

How many moles of water are there in one mole of hydrated salt?

Answers

Formula of hydrated sodium carbonate : Na₂CO₃.10H₂O, so moles of water in one mole of hydrated salt = 10

Further explanation

Hydrate is a compound that binds water (H₂O), usually in the form of crystals/ solids

If these compounds are dissolved in water or heated, the hydrates can decompose:

Example: X.YH₂O (s) → X (aq) + YH₂O (l)

The formula for the hydrated compound contains: YH2O

The mole ratio shows the ratio of the coefficients of the hydrate compound

10.45 hydrated sodium carbonate(Na₂CO₃.xH₂O) were heated until 3.87 of 3.87of anhydrous (Na₂CO₃) remained, so

mass H₂O released :

[tex]\tt 10.45-3.87=6.58~g[/tex]

mass Na₂CO₃ = 3.87 g

mol ratio Na₂CO₃(MW= g/mol) : H₂O(MW=18 g/mol) =

[tex]\tt \dfrac{3.87}{105,9888}\div \dfrac{6.58}{18}=0.0365\div 0.3655=1\div 10[/tex]

Answers

Answer:

Even though plants are rooted in the ground, they still move, exert force, and do work.

Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.

When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.

When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.

When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

Explanation:

Given parameters:

Time taken  = 17.2s

Velocity of the cart  = ?

Solution:

Velocity of a body is the the displacement divided by the time taken.

 Velocity  = [tex]\frac{displacement}{time}[/tex]
