Question

1) What is the mass in grams of a 51.2-mole sample of calcium?

Answer 1

2051.9936 g

Step-by-step explanation:

Mass = ?

Number of moles = 51.2 mol

The relationship between both quantities is given by the equation;

Number of moles = Mass / Molar mass

Solving for mass;

Mass = Number of moles * Molar mass

Mass = 51.2 * 40.078

Mass = 2051.9936 g
