Question

Which of the following contains maximum number of molecules?

पर्याय

• 1g CO₂

• 1g N₂

• 1g H₂

• 1g CH₄

Answer 1

1g H₂

ag of CO₂ = `1/44 xx 6.022 xx 10^23` molecules

= 1.368 x 10²² molecules

1g of N₂ = `1/28 xx 6.022 xx 10^23` molecules

= 2.15 × 10²² molecules

1g of H₂ = `1/2 xx 6.022 xx 10^23` molecules

= 3.011 × 10²³ molecules

1 g of CH4 = `1/16 xx 6.022 xx 10^23` molecules

= 3.76 × 10²² molecules
