Question

1. Calculate the mass of 1.000 mole of CaCl2

Show all your work. Answer in scientific notation when applicable.

Answer 1

Answer: 110 g/mol

Explanation:

First we need to find the molar mass of CaCl2 using the periodic table:

Ca: 40

Cl: 35 (Since Cl has a 2 at the end, multiply 35 by 2)

70+40= 110

Then multiply by amount of moles

110g×1.000mol = 110 g/mol
