Answer to Question #151795 in General Chemistry for Emily

Question

What is the mass of 3.40 x 10^22 molecules of glucose? C6H12O6

Answer 1

Molar mass of glucose , C6H12O6

= [(6×12)+(12×1)+(6×16)] g/mol

= 180 g/mol

6.023×10^23 molicules = 1 mole

So,Mass of

6.023×10^23 molicules of glucose = 180g

3.40 x 10^22 molicules of glucose = [3.40 x 10^22/(6.023×10^23)]×180 g

= 10.16 g

Hence, mass of 3.40 x 10^22 molecules of glucose = 10.16 g
