## How many moles are in 50g?

To calculate the weight of an element in grams to moles, we should know the molar mass of an element. For example, 50 grams of oxygen is equal to **3 moles**.

## How many moles are in 25 grams of hydrogen?

Answer: There are **2.77 moles** of hydrogen in 25 g of water.

## How many moles are in 20 grams of hydrogen?

Of mole =20/2=**10**. So answer is .

## What is the mole of H2?

The mass of one mole of H2 is **2.01588 grams** but some sources also list it as 2.016 grams. A molecule of H2 is formed when two hydrogen atoms bond…

## How many moles of hydrogen are in 100 grams of water?

Answer: One molecule of water has 2 atoms of hydrogen and one atom of oxygen. 1 mole of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2). This requires **100/18 moles** of hydrogen.

## How many moles is 8g of hydrogen?

Answer Expert Verified

= 3.01 x 10²³ moles. Therefore, 8 g of H₂ will have = 8 x 3.01 x 10²³ moles = **24.08 x 10²³ moles**. Thus, 8 g of H₂ will have 24.08 x 10²³ moles of hydrogen molecules.

## How do you find moles of hydrogen?

Use the mass of the hydrogen gas to calculate the gas moles directly; **divide the hydrogen weight by its molar mass of 2 g/mole**. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.

## How many moles are in hydrogen?

An amount of any substance in grams that is numerically equal to its atomic or molecular weight in amu has been defined as one mole of that substance. By this definition, one mole **of hydrogen** is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams.
