# If milk has a density of 1.03 g/mL, what is the mass of one quart, reported in kilograms?

Dec 11, 2016

Well, if $\text{1 quart}$ $\equiv$ $1200 \cdot m L$.............

#### Explanation:

$\text{Mass"="volume"xx"density}$

$= 1 \cdot {\text{quart"xx1200*mL*"quart}}^{-} 1 \times 1.03 \cdot g \cdot m {L}^{-} 1$.

We get an answer in the required units of $\text{grams}$, above $1200 \cdot g$.

Note that you will have to assess whether the conversion of $\text{quart}$ is correct. There are $\text{imperial pints}$ and $\text{US pints}$ with different volumes, and two of these may each make a $\text{quart}$.
