Diberikan sampel 1,5 mol CH⁴ (g) pada STP. (L = 6,02 x 10²³ molekul/mol dan volume molar = 22,4 L). Tentukan: B. banyak molekul sampel

Diberikan sampel 1,5 mol CH⁴ (g) pada STP. (L = 6,02 x 10²³ molekul/mol dan volume molar = 22,4 L). Tentukan:
B. banyak molekul sampel

Jawaban
9,03 x 10²³ molekul

Hubungan antara mol dengan jumlah molekul yaitu

Jumlah molekul = mol x bilangan avogadro ( L )

Dimana mol adalah satuan yang menunjukkan jumlah suatu atom atau senyawa.
Maka banyak molekul sampel CH₄

Jumlah molekul CH₄ = mol CH₄ x L
= 1,5 mol x 6,02 x 10²³ molekul/mol
= 9,03 x 10²³ molekul

Jadi, dapat disimpulkan bahwa banyak molekul sampel yaitu 9,03 x 10²³ molekul
