How many grams of can be prepared from of phosphorus? β Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
How many grams of $H_3PO_4$ can be prepared from $6.2\text{ g}$ of phosphorus?
Answer: A
π‘ Solution & Explanation
$P \rightarrow H_3PO_4$. By POAC on P: $\text{moles of } P = \text{moles of } H_3PO_4$. <br>$\text{Moles of } P = 6.2 / 31 = 0.2$. <br>$\text{Mass of } H_3PO_4 = 0.2 \times 98 = 19.6\text{ g}$.
