Question

Convert into moles and also calculate the number of molecules in 99g of carbon dioxide.​

Answer 1

Answer:

Molar mass of 1 mole of CO² = Molar mass of C +2 x Molar mass of O = 12 + 32 = 44.

⟹ 44 gm of CO²  = 1 mole of CO²

So, 22 gm of CO² = 22 moles of CO²  = 0.5

44

0.5 moles of C0 ²
