The concentration of total protein is 68 g/L.

#### Explanation:

The concentration of total protein in blood serum is usually expressed in grams per litre.

Our job, then, is to calculate the grams of protein in 1 L of serum.

$\text{mass of protein" = 1000 color(red)(cancel(color(black)("mL serum"))) × "1.02 g protein"/(15 color(red)(cancel(color(black)("mL serum")))) = "68 g protein}$

The concentration of total protein is 68 g/L.

This is right in the middle of the reference range for total protein, which is typically 60-80 g/L.
