Question

Predicting the units of the solution to a basic quantitative... A student sets up the following equation to solve a problem in solution stoichiometry. (The ? stands for a number the student is going to calculate.) Enter the units of the student's answer. (0.22L)×(1 mL/10‐³ L)×(1.57g/mL)/(61.04 g/mol) = ?​

Answer 1

(0.22 L) × (1 mL/10^-3 L) × (1.57 g/mL) / (61.04 g/mol) = ?

First, let's simplify the units:

(0.22 L) × (1000 mL/1 L) × (1.57 g/mL) / (61.04 g/mol) = ?

(0.22 L) × (1570 g/mol) / (61.04 g/mol) = ?

Now we can cancel out the units of g/mol:

(0.22 L) × (1570/61.04) = ?

(0.22 L) × 25.73 = ?

5.66 L·g

Therefore, the units of the student's answer are L·g.
