1 Expert Answer

Hydrogen has an atomic weight of 1; and oxygen has an atomic weight of 16 (check the periodic table for the atomic weights). So, one mole of water has a mass of 16 +1+1 = 18 grams. So, if one mole has a mass of 18 grams, 25 grams would have a mass of 25 grams/ 18 grams per mole or 1.39 moles.

How do you find the number of moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

How many moles are there in 40g of caco3?

Answer. 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 grams of oxygen is present in 50g of CaCO3?

Calculate the number of oxygen atoms and its mass in 50 g 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.
