Question

number of N atoms in 0.2 mole of N2H4​

Answer 1

Answer:

1 mole of N2H4 weighs = 2×14+4×1

                                       = 28+4 = 32 g

wt of 6.023×10²³ molecule of N2H4= 32g

N2 = 14×2=28g

Wt of 6.023×10²³atoms of N2 = 28g

Number of atoms in 1 mole = 6.023×10²³atoms

Number of N atoms in 0.2 mole = 6.023×10²³×0.2

                                                     = 1.2046×10²³ atoms
