A student measures the mass of a substance as 1.7132kg and it's volume as 0.65l. What is the density substance in g/mL? Round yo
Anna007 [38]

Answer:

The substance has a density of 2.636 grams per mililiter.

Explanation:

We must remember that density (\rho), measured in grams per mililiters, is the mass of the substance (m), measured in grams, divided by its volume (V), measured in mililiters. That is:

\rho = \frac{m}{V}

In addition, a kilogram equals 1000 grams and a liter equals 1000 mililiters. If we know that m = 1713.2\,g and V = 650\,mL, then:

\rho = \frac{1713.2\,g}{650\,mL}

\rho = 2.636\,\frac{g}{mL}

The substance has a density of 2.636 grams per mililiter.
