Question

The density of mercury is 13.54 g/cm3. Suppose you need 40 gm of mercury for an experiment. What volume of mercury do you need?

A. 2.95 cm3
B. 541.60 cm3
C. 26.46 cm3

Answer 1

The formula for density is:
Density= mass/ volume
Which means the formula for volume will be;
Volume= mass/ density
Which means the formula for volume will be
You were given the density as 13.54g/cm3 and the mass as 40gm. Just use them in the formula. That will be
Volume= 40/13.54
And that is 2.95 which is A. Hope I helped. Have a nice day
