Answer:
49.1 g
Explanation:
First we <u>convert 9.67x10²³ atoms of oxygen into moles</u>, using <em>Avogadro's number</em>:
- 9.67x10²³ atoms ÷ 6.023x10²³ atoms/mol = 1.60 mol O
Then we <u>calculate how many P₃O₉ moles there would be with 1.60 O moles</u>:
- 1.60 mol O *
= 0.18 mol P₃O₉
Finally we convert 0.18 P₃O₉ moles into grams, using its molar mass:
- 0.18 mol P₃O₉ * 237 g/mol = 49.1 g
