Question

what will be the mass of one C12 atom in gm

Answer 1

Mass of one mole of C12 = 12 g. so mass of 1 atom of C12 = 1.9927e-23 g. ... When you multiply it by 12 you again get mass ofC12 atom in gram, but do not use amu unit with 12 because here 12 is the number of particles each having mass of 1.66e-24.

please mark as brilliant ☺☺
