Question

The density of a test tube is 2.3g/cm3. The volume of the test tube is 4 cm3. What is

the mass of the test tube?

A. 0.92 g

B. 9.2g

C. 9.3g

D. 92g

Answer 1

B. 9.2g

Step-by-step explanation:

Density is mass over volume:

d=m/v

Let's plug in the values:

2.3=m/4

Now we solve like an equation:

2.3*4=(m/4)*4

9.2=m
