The answer is D . I hope this help you :) .
Answer:
<h2>mass = 200.23 g</h2>
Explanation:
The density of a substance can be found by using the formula

Since we are finding the mass
<h3>mass = Density × volume</h3>
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
<h3>mass = 200.23 g to 2 decimal places</h3>
Hope this helps you
