A conical flask whose tare mass is 241.3*g241.3g is filled to the mark with water, and the new mass is 489.1*g489.1g. What is the mass of the flask and contents when filled with chloroform, for which rho=1.48*g*cm^-3ρ=1.48gcm3?

"Density"(rho)="Mass"/"Volume" Density(ρ)=MassVolume

Explanation:

Given the above,

"Volume"Volume == "Mass"/rhoMassρ == ((489.1-241.3)*cancelg)/(1.00*cancelg*cm^-3)~=250*cm^3. Note how the dimensions cancel to give me an answer in cm^3, as is required for a volume.

Given a (rough) volume of 250*cm^3, the mass of the flask, when full with chloroform,

= 250*cancel(cm^3)xx1.48*g*cancel(cm^-3)+241.3*g=??g
