Need converting 4.82 mmol of diphenylmethanol to grams (c13h12o)?

0.89 g

We are given;

We are required to convert moles to mass in grams

In this case;

But, 1 mol = 1000 mmol

Thus, 4.82 mmol = 0.00482 moles

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

the answer is c.the valence of the atoms combine .

the objects have the same charge is correct.
