$9.88gCaSO_{4}$

Explanation:

1. Find the balanced equation:

$CaO+H_{2}SO_{4}=CaSO_{4}+H_{2}O$

2. Find the molecular weight of the $CaSO_{4}$

Atomic weight of Ca = 40 $\frac{g}{mol}$

Atomic weight of S = 32 $\frac{g}{mol}$

Atomic weight of O = 16 $\frac{g}{mol}$

Molecular weight of $CaSO_{4}$ = 40 + 32 + (4*16)

Molecular weight of $CaSO_{4}$ = 136 $\frac{g}{mol}$

3. Use the stoichiometry to find the mass of $CaSO_{4}$ that can be produced:

$4.070gCaO*\frac{1molCaO}{56gCaO}*\frac{1molCaSO_{4}}{1molCaO}*\frac{136gCaO}{1molCaSO_{4}}=9.88gCaSO_{4}$

The answer is: [B]: A small amount of solute is dissolved in a larger amount of solvent.

Note: In a solution, the solvent is the medium for which the substance (or, solute), is to be dissolved.
