8,4 liters of nitrous oxide at STP contain 2,65 moles.
16,8 L of Xe gas at STP is equivalent to 0,754 moles.
4 g of Helium = 1 mole.So, 56 g of helium = 14 moles

The volume is 0.887 L.
1 mole occupies 22.414 liters So, 3.30 moles will occupy 73.966 liters.

At STP, 1 mole of any gas occupies 22.4 L. Therefore, in a 5L sample of argon at STP, there would be 5/22.4 moles of argon, which is approximately 0.223 moles.
The answer is 2,68 moles.
The answer is 0,2675 moles.
At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 liters. Therefore, in 1.00 L, there would be 1/22.4 = 0.0446 moles of helium.
The volume of 10.9 mol of helium at STP is 50 litres.
