Question$$3 \mathrm{KOH}+\mathrm{H}_{3} \mathrm{PO}_{4} \rightarrow \mathrm{~K}_{3} \mathrm{PO}_{4}+3 \mathrm{H}_{2} \mathrm{O}$$ how many grams of potassium phosphate, $\mathrm{K}_{3} \mathrm{PO}_{4}$, are produced from 30.3 g of potassium hydroxide, KOH ? mass of potassium phosphate: $\square$

Studdy Solution
Calculate the mass of $\mathrm{K}_{3} \mathrm{PO}_{4}$.
Using the formula: $\text{Mass of } \mathrm{K}_{3} \mathrm{PO}_{4} = \text{Moles of } \mathrm{K}_{3} \mathrm{PO}_{4} \times \text{Molar mass of } \mathrm{K}_{3} \mathrm{PO}_{4}$
$\text{Mass of } \mathrm{K}_{3} \mathrm{PO}_{4} = 0.180 \text{ moles} \times 212.27 \text{ g/mol} \approx 38.21 \text{ g}$
The mass of potassium phosphate produced is:
$\boxed{38.21 \text{ g}}$
