Solve each of the following problems using dimensional analysis.

453.6 g

Explanation:

The following data were obtained from the question:

Mole of Ag = 4.2 moles

Weight (in grams) of Ag =?

Thus, we can obtain the weight in grams of Ag by doing the following:

Mole of Ag = 4.2 moles

Molar mass of Ag = 108 g/mol

Mass of Ag =.?

Mole = mass /Molar mass

4.2 = mass of Ag /108

Cross multiply

Mass of Ag = 4.2 × 108

Mass of Ag = 453.6 g

Thus, the weight (in grams) of 4.2 moles of Ag is 453.6 g
