## How many moles of CaCl2 are there?

The molar mass of CaCl_{2} is 110.98 g/mol. The conversion factor that can be used is then based on the equality that 1 mol = 110.98 g CaCl_{2}. Dimensional analysis will allow you to calculate the mass of CaCl_{2} that you should measure. When you measure the mass of 333 g of CaCl_{2}, you are measuring **3.00 moles** of CaCl_{2}.

## How many moles are in CaCl2 2h2o?

Calculate how many moles of CaCl2•2H2O are present in 1.50 g of CaCl2•2H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl2•2H2O.

…

Initial: CaCl2 x 2H20 (g) | 1.50 g |
---|---|

Initial: CaCl2 (mol) | 0.0102 mol |

Initial: NaCO3 (mol) | 106 g/mol |

Initial: NaCO3 (g) | |

Theoretical: CaCO3 | 1.02 g |

## What is meant by 1 mole?

A mole is the **amount (10) of material containing 6.02214 × 10 ^{23} particles**. 1 mol = 6.02214 × 10

^{23}particles. This number is also called Avogadro’s number… …

## How do I calculate moles?

So in order to calculate the number of moles of any substance present in the sample, we simply **divide the given weight of the substance by its molar mass**. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.
