Which sample has the greatest mass? (multiple choice) First of all, it's always a good idea to start with what a mole actually means, that way you can be sure that you know what you're looking at here. nceptual (A) 1 mole of marshmallows (B) 1 mole of Pb (lead) atoms (C) 1 mole of CO2 (carbon dioxide) molecules (D) All of these. The mass of each compound is as follows: 15. What is the molar mass of calcium carbonate (CaCO3)? In order to answer this question, we must first understand what a mole is. Which of the following has the greatest mass? By the end of this section, you will be able to: The identity of a substance is defined not only by the types of atoms or ions it contains, but by the quantity of each type of atom or ion. Consistent with its definition as an amount unit, 1 mole of any element contains the same number of atoms as 1 mole of any other element. Another factor to consider is volume. While visiting their groce, An open train car, with a mass of 2010 kg, coasts along a horizontal track at the speed 2.53 m/s.
