Question

What volume will 454.5 grams of Hydrogen gas occupy at 1.050 atm and 25.00 ℃? (Don’t forget Hydrogen gas is diatomic - H2.

Answer 1

Answer: The volume occupied by the gas is 5295.1 L

Step-by-step explanation:

To calculate the number of moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

Given mass of hydrogen gas = 454.5 g

Molar mass of hydrogen gas = 2 g/mol

Putting values in above equation, we get:

`\text{Moles of hydrogen gas}=(454.5g)/(2g/mol)=227.25mol`

To calculate the volume, we use the equation given by ideal gas equation:

PV=nRT

where,

P = pressure of the gas = 1.050 at m

V = Volume of gas = ?

n = number of moles of gas = 227.25 moles

R = Gas constant =
`0.0821\text{ L atm }mol^(-1)K^(-1)`

T = temperature of the gas =

Hence, the volume occupied by the gas is 5295.1 L

Answer 2

5.24×10^3 L

Step-by-step explanation:

Considering the volume occupied by 454.5g of H2 at 1.050 atm and 25°C.

Likewise, using ideal gas equation.

pV = nRT
