Question

what will be the mass of 100 atoms of hydrogen
a.100g
b.1.66×10-22g
c.6.023×10to the power of 23
d.100×6.023×10to the power of 23
plzzz it's too urgent...plzzz ​

Answer 1

Answer:

Then the answer change to 1.007*100= 100.7 amu.

Answer 2

Answer:

The answer is 1.66 to the power -22 g

Explanation:

1) 100 atoms of hydrogen =100 amu

2) Actual mass of hydrogen in grams :1.6735575 × 10^-24 g

Mass of 100 atoms=1.66×10^(-24)× 100

=1.66 × 10^(-22) gram

3)No. of particles in a mole(Avagadro's no.)

4) 100× Avagadro's no.
