Answer:

0.133 g

Explanation:

Pre-Solving

We are given that a chemist adds 525.0 mL of a calcium sulfate solution to a flask.

We know that the density of calcium sulfate is 0.253 g/L.

We want to know how much calcium sulfate (in grams) was added to the flask in three significant figures.

Solving

First, convert from mL to L.

525.0 mL => 0.5250 L

Now, multiply this volume by the density to get the amount of grams.

[tex]0.5250 L * \frac{0.253 g}{1 L } = 0.133 g[/tex] (rounded to three significant figures).
