Question

find the total number of molecules present in 6.6 gram of carbon dioxide​

Answer 1

Answer:

90.33 * 10²⁵

Explanation:

No. of molecules in 6.6g of CO₂

Mass of 1 mole of CO₂ - 44g.

No. of mole in 6.6g of CO₂ = 6.6/44 = 66/(44*10)  = 0.15.

∵No. of molecules in 1 mole of CO₂ = 6.022 * 10²⁷.

∴No. of molecules in 0.15 mole of CO₂ = 90.33 * 10²⁵
