Question 1 Report

220g of carbon dioxide contains ----- moles
Answer Details
220g of carbon dioxide contains 6 moles. In chemistry, the number of moles of a substance can be calculated from its mass using the concept of molar mass. Molar mass is the mass of one mole of a substance and is usually expressed in units of grams per mole (g/mol). For carbon dioxide, the molar mass is 44.01 g/mol. To convert the mass of a substance to the number of moles, divide the mass by the molar mass. In this case, 220g / 44.01 g/mol = 5 moles.
