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

Answer:

#"Density"(rho)="Mass"/"Volume" #

Explanation:

Given the above,

#"Volume"# #=# #"Mass"/rho# #=# #((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#
