# Frequent question: How many moles are in 400 grams of CaCO3?

Contents

## How many moles are in 200 grams of caco3?

200 g / 40 g /mol =5 mol.

## How many moles are in 100 g of caco3?

Gram molar mass of CaCO3 is 100 g. So, 100 g CaCO3 contains 1 mole of it.

## How many moles are in 40.0 g of caco3?

Step 1: Convert 40.0 grams of CaCO3 to moles by using the molar mass 100 g/mole. mole fraction of solute CaCO3 = 0.200. Hence total moles of solute and solvent in the solution is 2.00 moles. moles of solution = moles of solute ( CaCO3 ) + moles of solvent ( H2O).

## What is the gram atomic weight?

gram-atomic weight, amount of an atomic substance whose weight, in grams, is numerically equal to the atomic weight of that substance. For example, 1 gram-atomic weight of atomic oxygen, O (atomic weight approximately 16), is 16 grams.
