Mass = no. of moles x molecular weight
m = n x Mr
m = 2.5 mol x (24 + [16 x 2])
m = 140g
Answer:
<h3>The answer is 1.5 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question we have

We have the final answer as
<h3>1.5 g/mL</h3>
Hope this helps you
.100 mol CO2 x
