Question

the volume of 1.0 g of hydrogen at NTP is​

Answer 1

Answer:

According to the universal gas constant, 1 mole of ANY gas at STP occupies 22.4 L of space, and since the molar mass of Hydrogen is 1 g, we can say that 1 g of Hydrogen=one mole of Hydrogen, so 1 g of Hydrogen occupies 22.4 L of space.

Answer 2

Volume of 1.0 g of hydrogen at NTP is​ 11.2 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

According to the ideal gas equation:

$PV=nRT$

P = Pressure of the gas = 1 atm

V= Volume of the gas = ?

T= Temperature of the gas = 273 K      

R= Gas constant = 0.0821 atmL/K mol

n=  moles of gas= $\frac{\text {given mass}}{\text {Molar Mass}}=\frac{1.0g}{2g/mol}=0.50mol$

$V=\frac{nRT}{P}=\frac{0.50\times 0.0821\times 273}{1}=11.2L$

Thus volume of 1.0 g of hydrogen at NTP is​ 11.2 L
