## How many moles is 5 grams?

How many moles are 5 grams of calcium ? (Atomic mass of calcium =40u). Thus, there are **0.125 mole** in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

## How many moles is 5g of water?

**5/18 moles** for 5 grams of water.

## How many moles are there in 5g of calcium?

Molar mass of Calcium=40.078 g/mol. So numbers of moles =5.00/40.078=**0.125 mol**.

## How many atoms of sodium are there in 0.2 moles sodium atoms?

We know that 1 mole of atoms contains 6.022×1023 atoms. Thus, 0.2 mole of sodium element has **12.044×1022 atoms** in it.

## How many moles are in sodium chloride?

**One mol** of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

## How do you find moles of sodium chloride?

One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio **of 1:1** so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.

## 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 a sodium atom?

**ONE MOLE** of any element has 6.023×1023 atoms of that element. Therefore 1 mole or 22.99 grams of Na = 6.023×1023 atoms of Na. Avogadro’s Number is 6.023×1023.
