Explanation:

Answer:

A methane molecule is made from one carbon atom and four hydrogen atoms. Carbon has a mass of 12.011 u and hydrogen has a mass of 1.008 u. This means that the mass of one methane molecule is 12.011 u + (4 × 1.008u), or 16.043 u. This means that one mole of methane has a mass of 16.043 grams.

メタン分子は、1つの炭素原子と4つの水素原子から作られています。炭素の質量は12.011uで、水素の質量は1.008uです。これは、1つのメタン分子の質量が12.011 u +（4×1.008u）、つまり16.043uであることを意味します。これは、1モルのメタンの質量が16.043グラムであることを意味します。^>^

The mass of 0.10 mole of methane (CH4) is 1.6grams.

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;

mass = moles × molar mass

According to this question, there are 0.10 mole in methane (CH4). The molar mass of CH4 is 16g/mol.

Mass of CH4 = 0.10 × 16

Mass of methane = 1.6grams.

Therefore, the mass of 0.10 mole of methane (CH4) is 1.6grams.

Answer:

If the atmospheric pressure is lower than 760 torr, then the boiling temperature will be less than 100equationC.

B. 97.7°C

Explanation:

The question mentions the fact that temperature and pressure are directly proportional. This means that if one quantity is increasing the other increases simultaneously and vice versa.

Hence, if the atmospheric pressure is lower than 760 torr, then the boiling temperature will be less than 100equationC.

From;

PαT

P=kT

Hence

P/T = k

P1/T1 = P2/T2

P1T2 = P2T1

P1 =  760 torr

T1 = 94°C

T2 = ?

P2 = 790 torr

T2 =  P2T1/P1

T2 = 790 * 94/760

T2 = 97.7°C

Answer:

11.5 or 11.52, depending on however many decimal places you round it to

Explanation:

the equation for mass ( using the specific heat capacity equation) is energy transferred divided by temperature change x the specific heat capacity.

so, we do 725 ÷ 32° (the temp change) x 2.03 = 11.52 or 11.5, depending on how many decimal places you round to

i would round to 2 decimal places, so the answer would be 11.52kg.

mass is measured in kg :) hope this helped.

A 1.26 g sample of He gas has a pressure of 0.123 arm and a volume of 32.6 L, then the temperature of the gas is -117.7 degree C.

Temperature of any gas will be calculated by using the ideal gas equation as:

PV = nRT, where

P = pressure of gas = 0.123 atm

V = volume of gas = 32.6 L

R = universal gas constant = 0.082 L.atm / K.mol

T = temperature of gas = ?

n is moles of He gas and will be calculated as:

n = W/M, where

W = given mass = 1.26g

M = molar mass = 4 g/mol

n = 1.26 / 4 = 0.315 moles

On putting values we get,

T = (0.123)(32.6) / (0.315)(0.082)

T = 155.41 K = 155.41 - 273.15 = -117.7 degree C

Hence required temperature of the helium sample is -117.7 degree C.

Answer:

Molarity of HCl = 1.6M

Explanation:

The chemical reaction equation is;

HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)

Now, molarity = number of moles/volume

Thus, for NaOH, we have;

Number of moles = molarity × volume = 2M × (20/1000) L

Number of moles = 0.04 moles

Using the coefficients in the chemical equation above, we can find the corresponding number of moles for HCl.

Number of moles of HCl = 0.04 moles NaOH × (1 mole of HCl/1 mole of HCl) = 0.04 moles of HCl

Thus;

Molarity of HCl = 0.04/(25/1000)

Molarity of HCl = 1.6M

Answer:

63.58 g O

Explanation:

To calculate the mass of O atoms, the number of moles of O atoms are needed and can be calculated as follows:

n (no. of moles) = nA ÷ 6.02 × 10^23

n = 2.393 x 10^24 ÷ 6.02 × 10^23

n = 0.398 × 10^ (24-23)

n = 0.398 × 10^1

n = 3.98moles.

To calculate the mass of Oxygen, we use the following formula:

moles = mass/molar mass

Molar mass of O = 16.

3.98 = m/16

m = 3.98 × 16

m = 63.68grams of Oxygen.

Answer:

Solution given:

[tex]1 mole \:of O=6.023×10^{23} atoms[/tex]

1 mole of O =16g

we have

[tex] 6.023×10^{23} atoms\: of O=16g[/tex]

now

[tex] 2.393 × 10^{24} atoms\: of \:O\\=16/6.023×10^{23}*2.393 x 10^{24}g\\=63.57g[/tex]

63.57g is a required mass of O.
