## How do I calculate moles?

1. First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
2. For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## What is the mass of 0.5 mole of CaCO3?

Weight of 0.5 moles of CaCO3​ = 1100​×0. 5 = 50g.

## How many moles are in 50g of CaCO3?

100g Caco3=1mole.. , 50g of caco3=1÷100×50=0.5 mol..

100.0869 g/mol

## How many moles of caco3 is 3 days?

## How many moles of oxygen O are in 1 mole of calcium carbonate caco3 )?

Answer and Explanation: 3 moles of oxygen are present in one mole of calcium carbonate.

=100.1 g/mol.

## How many moles are in 32 grams of oxygen?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## Why is mole concept important?

Explanation: THE mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.
