Question-01 Find the number of moles present in 0.448 L of dihydrogen at STP.
(A) 0.08 mol
(B) 0.06 mol
(C) 0.04 mol
(D) 0.02 mol
Answer : (D)
Explanation:
No. of moles of a gas (n) = Volume of the gas at STP / Molar volume of the gas
= 0.448 L / 22.4 L/mol
n = 0.02 mol of H₂
∴ No. of moles of dihydrogen in 0.448 L at STP will be 0.02 mol.
