density = mass/volume
mass = 127g
volume = 32.1ml = 32.1 cm^3
density =127/32.1 g/cm^3 = 3.96g/cm^3

um if i understand correctly your trying to find the density of a rock and u must use significant figures okay so
d=m/v
d=127/32.1
d=3.956386
okay since your doing division you use the number with the least amount of numbers in the whole problem and both have 3 so it doesnt matter
d=3.96
