Question

How many molecules are in 2.30 x 10^-3 g of C6H1206 answer in molecule

Answer 1

First, find the molar mass of C6H12O6 (180.156 g/mol)

Then, using avagadro's number (6.02*10^23), find the amount of molecules in the sample.

(2.3*10^-3g)/180.156 g/mol = 0.0000128 mol
(0.0000128 mol)(6.02*10^23)= 7.6856*10^18 molecules
