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

Solution — Molecular mass of CaCO3= 40+12+3×16 = 100 No. mole of CaCO3 = 50g/100g = 0.5 0.5 mole of CaCO3 contains 1.5 moles of oxygen atoms No. of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.

## How many moles is 50g of CaCO3?

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

## What is the mass of 0.01 moles of CaCO3?

weight of 0.01 moles of calcium carbonate is 0.4 gram.

## What are the oxygen moles in 0.5 mol of CaCO3?

Answer: Moles of oxygen in 0.5 mol of CaCO3 is 1.5 mole. 1 mole of CaCO3 gives 1 mole of CaO and 1 mole of oxygen. Any substance has molecular mass in 1 mole so mass of 1 mole CaCO3 is 100 gram.

=100.1 g/mol.

## What is the mass in grams of 2 moles of calcium carbonate CaCO3 )?

Explanation: The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Calcium Carbonate, or 100.0869 grams.

## How many moles are in 20 grams of CA?

Atomic mass is the sum of protons (or electrons) and neutrons in an atom. For example, there are 20 neutrons and 20 protons in Calcium, so 20+20=40u is the atomic mass of Ca.

## How many moles are in 63 grams of CaCO3?

0.638 moles in 63.8g of calcium carbonate.

## How many moles are in 10g of CaCO3?

Therefore, number of moles in 10g of calcium carbonate is 0.1.
