Dimensional Analysis Ex. 3.55m=355cm
how many centimeters are there in 3.55m
quantity given: 3.55m
3.55m * (100cm/1m)=


Density converted between mass and p=0.785g/ml
volume of a substance
30.2ml sample of ethyl alcohol with a mass
of 23.71002g


Find mass of and object. density of alcohol 1.5784g=1.5g
is 0.7892g/mL, so alcohol is 0.7892g per 1ml.
determine the mass of alcohol for 2.0mL use


Density = mass/__________ volume


Density of an object? density = 1.7156g/mL= 1.72g/ml
mass of 2.4019 and volume of 1.40mL


Density of an object? density= 0.3825g/mL=0.38g/mL
volume of 32mL and a mass of 12.24g


density of an object? density= 5.507g/cm= 5.51g/cm^3
mass of 78.2g/14.2cm^3


density of an object? density= 2.43686g/cm^3= 2.4g/cm^3
22.57cm^3/55g
