The balance equation is :
<span>SO2 + CaO → CaSO3 
</span>
1.
<span>(2100 tons) x (0.025 S) / (32.0655 g S/mol) x (1 mol SO2 / 1 mol S) x </span>
<span>(1 mol CaO / 1 mol SO2) x (56.0778 g CaO/mol)
= 91.81 tons CaO 
</span>
2. <span>(2100 tons) x (0.025 S) x (907185 g/ton) / (32.0655 g S/mol) x (1 mol SO2 / 1 mol S) x </span><span>(1 mol CaSO3 / 1 mol SO2) x (120.1422 g CaSO3/mol)
= 1.784 x 10^8 g CaSO3</span>

Good morning, I have a question..
matrenka [14]

Answer:

<h3>The answer is 5.24 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 152 g

density = 29 g/cm³

We have

volume =  \frac{152}{29}  \\  = 5.24137931...

We have the final answer as

<h3>5.24 mL</h3>

Hope this helps you
