Question

Need help converting 4.82 mmol of diphenylmethanol to grams (C13H12O)?

Answer 1

Answer:

0.89 g

Explanation:

We are given;

• 4.82 mmol of Diphenylmethanol

We are required to convert moles to mass in grams

• We need to know the relationship between mass, moles and molar mass

• $Moles =\frac{Mass}{Molar mass}$

• Therefore, when we have molar mass and moles of a compound;

$Mass=(moles)(molar mass)$

In this case;

• We need to know the molar mass of diphenylmethanol
• Molar mass of C₁₃H₁₂O = 184.234 g/mol

But, 1 mol = 1000 mmol

Thus, 4.82 mmol = 0.00482 moles

• Therefore;

Mass of C₁₃H₁₂O = 0.00482 moles × 184.234 g/mol

                           = 0.888 g

                           = 0.89 g

Thus, the mass of C₁₃H₁₂O in 4.82 mmol is 0.89 g
