## How many atoms are there in 50 grams of CaCO3?

How many atoms of each constituent element are present in 50 g of CaCO_(3) ? 50.0 grams of CaCO3=50.0100.0=0.5 gram mol. 0.5 gram mole of CaCO3 contain oxygen atoms =0.5×3×6.022×1023=**9.03×1023 atoms**.

## How many moles are there in 40g of CaCO3?

Calcium carbonate is CaCO3 so there is (in **one mole**) 40g of calcium because there would be one mole of that, 12g of carbon because there would be one mole of that, and 48g of oxygen because there are three moles of that.

## How many moles are there in 100g of CaCO3?

Solution — Molar mass (Molecular mass in gram) of CaCO3 = 40+12+3×16 = 100 g No. of moles of CaCO3 = No. of molecules/Avogadro constant = 6.022 × 1023/ 6.022 × 1023 = **1 mole** Mass of CaCO3 = No. of moles × molar mass = 1 × 100 g = 100 g.

## How many moles are in 24.5 g of CaCO3?

weight of calcium carbonate given= 25 g. = **0.25 moles**.

## How many molecules of Ca are present in 100g of CaCO3 CA 40g?

Therefore, 100 g of calcium carbonate contains **6.022×1022 molecules**.

## How many atoms of each element is in CaCO3?

Calcium carbonate is a molecule that contains **one atom of calcium, one atom of carbon, and three atoms of oxygen**.

## How many moles of oxygen atoms are there in 1 mole CaCO3?

Answer (1 of 1): There are **three moles** of oxygen in one mole of Calcium Carbonate or CaCO3.So in 5.79 moles of CaCO3 the number of Oxygen moles = 5.79 x 3in 5.79 moles of CaCO3 the number of Oxygen moles = 17.37 molesin one mole of Oxygen the number of atoms = 6.023 x 10^26in 17.37 moles of Oxygen the number of atoms= …

## Which one has a greater number of carbon atoms 50g of CaCO3 50g of Na2CO3?

Therefore, 50 g CaCO3 and 53 g of Na2CO3 have the same number of calcium carbonate and **sodium carbonate** molecules, which is half of Avogadro constant, 3.011 * 10 to the power 23. So, they also contain the same number of carbon atoms. Thus, 50 g of CaCO3 has more carbon atoms than 50 g of Na2CO3.
