1. Understand Density

Density is a measure of how much mass is contained in a given volume. The formula for density is:

* Density (D) = Mass (M) / Volume (V)

2. Rearrange the Formula to Solve for Mass

We want to find the mass, so let's rearrange the formula:

* Mass (M) = Density (D) * Volume (V)

3. Plug in the Values

* Density (D) = 1.05 g/mL

* Volume (V) = 575 mL

4. Calculate the Mass

* Mass (M) = (1.05 g/mL) * (575 mL)

* Mass (M) = 603.75 g

Answer: 575 mL of the 18.0% ammonium chloride solution contains approximately 603.75 grams.
