# A beaker whose mass was 345.8*g was filled with a 225*mL volume of carbon tetrachloride, to give a combined mass of 703.55*g. Given these data, what is rho_"carbon tetrachloride"?

Dec 17, 2016

${\rho}_{\text{carbon tetrachloride"="Mass of carbon tetrachloride"/"Volume of carbon tetrachloride}}$

#### Explanation:

And so we put the given numbers in:

rho_"carbon tetrachloride"=(703.55*g-345.8*g)/(225*mL)=??g*mL^-1

Because $1 \cdot g \cdot m {L}^{-} 1 = 1 \times {10}^{-} 3 k g \cdot {\left({10}^{-} 3 L\right)}^{-} 1 = 1 \times {10}^{-} 3 k g \times {10}^{3} \cdot {L}^{-} 1 = k g \cdot {L}^{-} 1$, the $\text{density}$ has the same figures in $k g \cdot {L}^{-} 1$.

$\text{Carbon tetrachloride}$ will form an immiscible layer with water. Will it float? How can you tell from these figures?
