Answer:
C₅H₁₀O₅
Explanation:
Let's consider a compound with the empirical formula CH₂O. In order to determine the molecular formula, we have to calculate "n", so that
n = molar mass of the molecular formula / molar mass of the empirical formula
The molar mass of the molecular formula is 150 g/mol.
The molar mass of the empirical formula is 12 + 2 × 1 + 16 = 30 g/mol
n = (150 g/mol) / (30 g/mol) = 5
Then, we multiply the empirical formula by 5.
CH₂O × 5 = C₅H₁₀O₅
Answer:

Explanation:
(a) Balanced equation
3ZnCO₃ + 2H₃PO₄ ⟶ Zn₃(PO₄)₂ + 3H₂O + 3CO₂
(b). Calculation
You want to convert moles of Zn₃(PO₄)₂ to moles of ZnCO₃
The molar ratio is 1 mol Zn₃(PO₄)₂:3 mol ZnCO₃

You need
to form 3.0 mol of Zn₃(PO₄)₂.
Answer: There are 0.499 moles present in
molecules of Boron trichloride.
Explanation:
According to mole concept, there are
molecules present in 1 mole of a substance.
Hence, number of moles present in
molecules are as follows.

Thus, we can conclude that there are 0.499 moles present in
molecules of Boron trichloride.
