Question

se the mass and volume data to calculate the density of mercury to the nearest tenth. Mass = 57 g Volume = 4.2 mL The density of mercury is g/cm3.

Answer 1

Its Mass divided by Volume. 57/4.2= 13.5g/cm3
if you have to round it, .5 and under :Leave it .6 and up: round it up 1.
so in this case, leave it at 13. Hope this helps

Answer 2

Density can be calculated using the following rule:
density = mass/volume
plug the given mass and volume into the equation to calculate thr density:
density=57/4.2 = 13.57 g/cm^3
