Question

If one mole of carbon atoms weighs 12gram, what is the mass( in gram) of 1 atom of carbon? for 5 mark​

Answer 1

1 mole of C weights 12g.

1 mole = 602,200,000,000,000,000,000,000

602,200,000,000,000,000,000,000 atoms of C weights 12g

1 atom of C weights $\frac{12}{602,200,000,000,000,000,000,000}$g

which is equalivent to 0.000000000000000000000199269g or 120.0026073 daltons.
