Answer :
Answer:
1.33 x 10^-3 mol H2
Explanation:
? mol H2 = 8.00 x 1020^20 molecules H2 x 1 mol H2/6.02 ! 1023 molecules H2 = 1.33 x 10^-3 mol H2
Hope that helps!
8.00 x 10²⁰ molecules of H₂ present in 1.33 x 10⁻³ mole of H₂.
What is mole?
Mole is used to define the amount of quantity of any substance and 1 mole equals to the 6.023 × 10²³ elementary entities or atoms in it.
According to the question:
1 mole of H₂ = 6.023 × 10²³ molecules of H₂
or 1 molecules of H₂ = 1 mole of H₂ / 6.023 × 10²³ molecules of H₂
To convert 8.00 x 10²⁰ molecules into mole we calculate as follow:
x mole of H₂ = (8.00 x 10²⁰ molecules x 1 mole of H₂) / 6.023 × 10²³ molecules
x mole = 1.33 x 10⁻³ mole
Hence, 1.33 x 10⁻³ mole of H₂ consist 8.00 x 10²⁰ molecules.
