The total number of protons in 10g of calcium carbonate is (N0
WebNov 23, 2024 · 1 mole of Caco3 weighs 100g. So, 100g of Caco3 contains 6 * 10^23 molecules. But, We are looking for 10g. So 100 -> 6 * 10^23. 10 -> x. x = 6 * 10^22 molecules. We know that, Number of protons in a molecule is directly its atomic number. So, Ca- 18. C - 6. O - 8 * 3 = 24. Totally, 50 protons and 50 electrons in one molecule of CaCO3. And now ... WebAnswer: Molar mass CaCO3 = 100g/mol You have 200g = 2 mol CaCO3 1 mol CaCO3 = 6.02*10^23 molecules 2 mol CaCO3 = 1.20*10^24 molecules In these calculations I will use: The atomic number ( always an exact whole number ) = number of protons and also the number of electrons.
