Question

What is the mass of substance that exactly fills a 247.2 mL container? The density of the substance is 0.81 g/mL. Give the answer with two decimals.

Answer 1

Answer:

mass = 200.23 g

Explanation:

The density of a substance can be found by using the formula

$Density = \frac{mass}{volume}$

Since we are finding the mass

mass = Density × volume

From the question

Density = 0.81 g/mL

volume = 247.2 mL

Substitute the values into the above formula and solve for the mass

mass = 0.81 × 247.2

= 200.232

We have the final answer as

mass = 200.23 g to 2 decimal places

Hope this helps you
