So you see the triangle with the letters, look at what you're given. you have mass and volume solving for density. So you take the mass and divide it by the volume. 15.2/15.5 which your answer is 0.98 or 1.0 that's your density.

The density of the unknown liquid is 0.981 g/mL

Your density triangle tells you that

D = m/V or density = mass/volume

So, D = (15.2 g)/(15.5 mL)

You divide numbers by numbers and units by units.

D = 15.2/15.5 g/mL =0.980 645 161 g/mL (by my calculator)

The answer can have no more than three significant figures, so you round off to three significant figures and get

D = 0.981 g/mL
