Calculate the mass of a substance with a density of 1.98 g/mL and a volume of 265 mL.
Vinvika [58]

Answer:

<h2>mass = 524.7 g</h2>

Explanation:

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

Density =  \frac{mass}{volume}

Making mass the subject we have

<h3>mass = Density × volume</h3>

From the question

Density = 1.98 g/mL

volume = 265 mL

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

That's

mass = 1.98 × 265

We have the final answer as

<h3>mass = 524.7 g</h3>

Hope this helps you
