Answer:
The mass of the substance is 60g
Explanation:
The formula to be used here is that of density
Density = mass ÷ volume
The density of the substance is 10.0 g/mL (according to the question) while the volume of the substance is 6.0 mL (according to the question). The mass of the substance (which is the unknown) can be determined from the formula provided above as
Mass = Density × volume
Mass = 10 × 6
Mass = 60g
