## 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).
