What is the molar volume of 3 moles of He at STP?
Answer. Answer: Explanation: Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=68.1 L .
What is molar volume of a gas?
At a given temperature and pressure , one mole of any gas occupies the same volume . The molar volume is the volume occupied by one mole of any gas, at room temperature and pressure. The molar volume is equal to 24 dm 3 (24,000 cm 3).
What is molar volume of a gas at STP?
This makes for a very useful approximation: any gas at STP has a volume of 22.4 L per mole of gas; that is, the molar volume at STP is 22.4 L/mol (Figure 6.3 “Molar Volume”).
What is the volume of 3 moles of neon gas at STP?
The answer is 1100L .
What is the volume of 3 moles of hydrogen gas at STP?
At STP, 1 mole of hydrogen can occupy a volume of 22.4 liters. At STP, 3 moles of hydrogen can occupy a volume of 2×22. 4=44. 8 liters.
What is the molar volume of 3?
Due to the new conditions of STP , the new molar volume using the ideal gas equation (PV=nRT) comes out as 22.7 L . 3mol ⋅22.7 Lmol =68.1 L .
What is molar volume Class 9?
The Molar Volume, represented by V m, is the volume occupied by one mole of a substance which can be a chemical element or a chemical compound at Standard Temperature and Pressure (STP). It can be calculated by dividing Molar mass (M) by mass density (ρ).
