The Mole Concept Worksheet Exercise A. Your instructor will have samples of the following: 1 mole of'S (sulfur) 1 mole of H?O (water) . 1 mole of CaCO, (calcium carbonate) • 1 mole of MgSO, 7H?O (magnesium sulfate heptahydrate) 1. Calculate the molar masses of each of these substances to two decimal places • 1 mole of S g • 1 mole of H?O g • 1 mole of CaCO, g . I mole of MgSO4.7H?O g 2. Relate the masses of the materials calculated with the amount of material in the sample. a Which sample has the largest volume? b. Which sample has the smallest volume? c. Does the sample with the largest volume also have the largest mass? Explain why or why not d. Which has the largest number of formula units (molecules)? Explain why or why not e. Which has the smallest number of formula units, (molecules)? Explain why or why not £ Which sample has the largest number of atoms? g. Which sample has the smallest number of atoms?
