Question

9.80 1. The density of mercury is 13600 kg/m³. What is this value in g/cm³? 2. Find the mass of water which will fit in a large tank measuring 2 m x 1 m x 20 cm. Density of water is 1000 kg/m³ or 1.0 g/cm³. 3. Find the volume of a lump of softwood whose mass is 120 g. Density of softwood is 0.6 gcm-3 or 600 kgm-³. -3​

Answer 1

Answer:

1. 13..6 grams per centimeters cubed.

2. Mass = 400kg

3. Volume = 200cm = 2m

Explanation:

1. The conversion for kg/m^3 to g/cm^3 is divide by 1000.

2. $density=\frac{mass}{volume}$

$1000=\frac{mass}{2 * 1 * 0.2}$

$1000*0.4=mass$

$400kg = mass$

3. $density=\frac{mass}{volume}$

$0.6=\frac{120}{volume}$

$volume=\frac{120}{0.6}$

$volume= 200cm$
