How do you find the number of protons in CaCO3?

1 mole of CaCO3​ weighs 100g.

  1. So, 100g of CaCO3​ contains 6×1023 molecules.
  2. 10g 6×1022 molecules.We know that,
  3. = Number of protons in 6×1022 molecules.
  4. = 50×6×1022.
  5. = 3×1024 protons.

What is the correct for 10 grams of CaCO3?

How many moles of calcium atoms are in each mole of calcium carbonate?

1 mole
You know that one mole of calcium carbonate contains 1 mole of calcium, one mole of carbon, and 3 moles of oxygen.

How do you convert from grams to moles?

To convert moles into grams, determine the number of moles preset and the molar mass of the compound. Multiply the number of moles by the molar mass to obtain the final answer in grams.

What is the molecular weight of CaCO3?

How to calculate moles from grams.?

– Multiply the number of atoms each element contributes to the compound by the atomic weight of that element. – Add the total weight of each element in the compound together. – For example, (NH 4) 2 S has a molecular weight of (2 x 14.01) + (8 x 1.01) + (1 x 32.07) = 68.17 g/mol. – Molecular mass is also referred to as molar mass.
