## How many grams are in 1 mole of hydrogen?

Because the molecular mass of Hydrogen is 1 gram/mole, there is **1 mole of hydrogen** in 1 gram of hydrogen atoms. For every mole, there are 6.02*10^{23} atoms, so in 1 gram of hydrogen there are 6.02*10^{23} hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.

## How many moles are in H?

Correct answer:

Avogadro’s number, 6.022 * 10^{23} is the number of things in **one mole**. The question indicates that there is 1 mole of H_{2}. Thus there are 6.022 * 10^{23} molecules of H_{2}.

## What is 1 mole in grams?

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**.

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

Answer: 1 mole of hydrogen gas weighs 2 gram so 2 moles weigh **4 grams** mate hope this helps.

## Is hydrogen H2 or H?

Hydrogen has a molar mass of 1 and it’s molecular formula is H2. Hydrogen, **H**, is the lightest element with the atomic number 1. It is a colorless, odorless, tasteless, and highly flammable gas with the molecular formula H2.

## What is the mass of 5 moles of H2?

Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = **10.08 g**.
