Q.
Calculate no. of Moles of Hydrogen molecules present
in 1.2044 x 1022 Hydrogen molecules Sample.​

Answer 1

Answer:

0.02 moles

Explanation:

1 mole = 6.022 × 10²³ particles

x moles = 1.2044 × 10²² particles

Using Unitary method,

x= (1.2044 × 10²²) ÷ (6.022 × 10²³ )

 = 0.2 ÷ 10

 =0.02 moles
