Question

A student measures the mass of a substance as 1.7132 kg and it’s volume as 0.65 L. What is the density of the substance in g/mL? Round your answer to the correct number of significant figures.

Answer 1

Answer:

$\rho =2.6g/mL$

Explanation:

Hello,

In this case, considering that the density is defined as:

$\rho =\frac{m}{V}$

Thus, since 1 kg equals 1000 g and 1 L equal 1000 mL, the required density in g/mL turns out:

$\rho =\frac{1.7132kg}{0.65L}*\frac{1000g}{1kg}*\frac{1L}{1000mL} \\\\\rho=2.6g/mL$

Take into account that since 0.65 L has two significant figures, the result is also shown with two significant figures.

Regards.
