volume of water delivered using a buret has a mass of 2.67 g. What was the final volume reading on the buret if the inital volume reading was 0.10 ml?
[assume the density of water is 1.00g/mL]

Density=mass/volume
Solve for volume,
mass/density=(2.67 g)/(1.00g/mL)=volume in mL
volume in mL+0.10mL=final volume 
,l,

What is the density of a block of unknown material with a mass of 18.17 g if the dimensions are:
length = 2.2 cm
height = 1.7 cm
width = 5.2 cm 
What is the density of a 19.99 g object if the dimensions of the block are:
length = 12.6 mm
height = 4.88 cm
width = 0.0140 m
