Question

2. Calculate the density of a rock that has a mass of 21.58 grams and causes the water in a

graduated cylinder to rise from 20.0yl to 25.4 ml.

Answer 1

4.00 g/mL

Step-by-step explanation:

Density is mass divided by volume (g/mL).

Mass of rock = 21.58

Volume of rock = 25.4 - 20.0 = 5.4mL

Density of rock = 21.58g / 5.4mL = 3.99629 g/mL

Round to the lowest number of significant figures which is three = 4.00 g/mL
