Question

- The number of hydrogen atoms in 2 moles of H2S
is:
a) 6.023 * 10% b) 1.204 x 1024
c) 1.807 * 1024
d) 2.409 x 1024
​

Answer 1

ANSWER:

no. of moles of Hydrogen atoms in 1 mole H2S = 2

no. of moles of Hydrogen atoms in 2 moles of H2S = 4

therefore... no. of Hydrogen atoms in 2 moles H2S = 4 × 6.022× 10^23

= 2.4088 × 10^24

= 2.409 × 10^24..

Therfore option (d) is correct.
