## How many moles are in sodium?

In grams, a mole is one formula mass. For example, **1 mol** of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table).

## How many moles are in 50 grams of water?

There are **3 moles** of O in 50 g.

## How many grams are in 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 there in 10 moles of sodium?

One mole of any substance is equal to the value of Avagadro number (6.023 x 10^{23}). It can be used to measure the products obtained from the chemical reaction. The unit is denoted by mol. ∴ The mass of 10 moles of sodium sulphite = **1260 grams**.

## How many grams are in 2.5 moles of sodium?

And since we know that 1⋅mol of sodium has a mass of 22.99⋅g , we got a mass of 2.50⋅mol×22.99⋅g⋅mol−1=**57.5⋅g** with respect ot sodium.

## How many moles are there in 5 grams of sodium?

Moles = mass / molar mass

So, **0.125 moles** are present in 5g of NaOH.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## How much would 3.000 moles of oxygen weigh?

1 Answer. 3 moles of Oxygen atoms weigh **48.00 grams**.

## How many moles of hydrogen are needed for 100 grams of water?

Unlock

1 mole of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2). This requires **100/18 moles** of hydrogen. As the molar mass of hydrogen is 2, it requires 200/18 = 100/9 g of hydrogen. It requires 100/9 g of hydrogen gas and 800/9 g of oxygen gas to make 100 g of water.
