## What is the mass of 2 moles?

Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

## How many atoms of helium are in 2 moles?

If I fill up a balloon with 2 moles of helium atoms, how many helium atoms would be in the balloon? If 1 mole of atoms is 6.02 x 1023 atoms, then 2 moles of atoms would be equal to 1.20 x 1024 atoms.

## What is the volume of 2 moles of helium gas at STP?

Explanation: Assuming that helium behaves as an ideal gas, we know that a mole of ideal gas occupies 22.4 litres at STP.

## What is the mass of 2.00 mole of he?

The molar mass is “4.002602 g/mol“. Socratic.

## What is the mass of 2.00 moles of carbon?

From the above concept of mole we tell that one mole of carbon contains [12g] of carbon, which is the molar mass of carbon. So the amount of carbon present in [2] moles of carbon =[2 times 12{text{ }}g = 24g].

## What is the mass of 2 moles of water?

One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
