## How many grams are in 2.00 moles?

2.00 mol Ne has a mass of 40.4 g .

## What is the mass of 2 mol Al?

The periodic table shows that the atomic mass (rounded to two decimal points) of Al is 26.98, so 1 mol of Al atoms has a mass of 26.98 g. According to the periodic table, 1 mol of U has a mass of 238.03 g, so the mass of 2 mol is twice that, or 476.06 g.

## How many moles are in 2 grams of he?

Once again, grams cancel out to give moles. So the answer is 2.0 moles of helium. So to recap, to convert moles to grams, we multiplied by the molar mass. To convert grams to moles, we divided by the molar mass.

## How many grams is a mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## How many grams are in 2 moles of HF?

Explanation: Normally 1 mole of F2 reacts with 1 mole of H2 giving 2 moles of HF (which is 20g).
