Answer:
<h3>The answer is 123.72 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 157 mL
density = 0.788 g/mL
We have
mass = 0.788 × 157 = 123.716
We have the final answer as
<h3>123.72 g</h3>
Hope this helps you
