# 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?

$\text{Density"(rho)="Mass"/"Volume}$

#### Explanation:

Given the above,

$\text{Volume}$ $=$ $\frac{\text{Mass}}{\rho}$ $=$ $\frac{\left(489.1 - 241.3\right) \cdot \cancel{g}}{1.00 \cdot \cancel{g} \cdot c {m}^{-} 3} \cong 250 \cdot c {m}^{3}$. Note how the dimensions cancel to give me an answer in $c {m}^{3}$, as is required for a volume.

Given a (rough) volume of $250 \cdot c {m}^{3}$, the mass of the flask, when full with chloroform,

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