Explanation:
distillation, process involving the conversion of a liquid into vapour that is subsequently condensed back to liquid form. ... This basic operation requires the use of a still or retort in which a liquid is heated, a condenser to cool the vapour, and a receiver to collect the distillate.

Add up all the molar masses of the elements multiplied by the number of atoms each.
Molar mass of carbon = 12.01g
Molar mass of hydrogen = 1.01g
Molar mass of oxygen = 16g
9(12.01) + 8(1.01) + 4(16)
Molar mass of aspirin = 180.17g

I have had this question on a test before!! Hope this helps
Answer:
mass = 100kg
Explanation:
Hello! In order to calculate the mass, we first have to calculate the volume of the tube.
For this, we have the area (A) and the length (L) of the tube.
V = A * L
A = 100cm2 * (1m2 / 10000cm2) = 0.02m2
L = 5m
V = 0.02m2 * 5m = 0.1m2
Then we can calculate the area from the density.
Density = mass / volume
mass = density * volume = 1000 (kg / m3) * 0.1m3
mass = 100kg
