Answer:
20.02 Liters
Explanation:
Mass = 35g
Volume = ?
Temperature = 301K
Pressure = 1.35 atm
The relationship between the quantities is given as;
PV = nRT
n = mass / Molar mass = 35 / 32 = 1.09375 mol
V = nRT / P
V = (1.09375 * 0.0821 * 301) / 1.35
V = 20.02 L
Answer:
0.357 g He
Explanation:
1 mol of gas at STP = 22.4 L
2.00 L * 1 mol/22.4 L = 0.08929 mol He
M(He) = 4.00 g/mol
0.08929 mol He * 4.00 g/ 1 mol He = 0.357 g He
