Question

empty mass = 250.0 g filled mass = 1300. g what is the density of the liquid?

Explanation:

Step1: Calculate mass of liquid

The mass of the empty cylinder is $m_{empty}=250.0\ g$ and the mass of the filled - cylinder is $m_{filled}=1300.0\ g$. The mass of the liquid $m$ is the difference between the mass of the filled - cylinder and the mass of the empty cylinder.
$m = m_{filled}-m_{empty}=1300.0 - 250.0=1050.0\ g$

Step2: Determine volume of liquid

The volume of the liquid $V$ is equal to the volume of the filled part of the cylinder. From the image, the volume of the liquid $V = 1000\ mL$. Since $1\ mL = 1\ cm^{3}$, $V = 1000\ cm^{3}$.

Step3: Calculate density of liquid

The density formula is $
ho=\frac{m}{V}$. Substitute $m = 1050.0\ g$ and $V = 1000\ cm^{3}$ into the formula.
$
ho=\frac{1050.0\ g}{1000\ cm^{3}} = 1.05\ g/cm^{3}$

Answer:

$1.05\ g/cm^{3}$
