Question

Menentukan mol yang berhubungan dengan jumlah molekul/partikel:

a) 6,02 * 10 ^ 22 molekul gas N_{2}

b) 3,01 * 10 ^ 24 atom natrium

c) 3, 1 * 10 ^ 23 molekul CH4 (L = 6,02 * 10 ^ 23)​

Answer 1

Jawaban:

1. 0,1 mol

2. 5 mol

3. 0,5 mol

Penjelasan:

1. N = 6,02 × 10^22

N = n × L

6,02 × 10^22 = n × 6,02 × 10^23

n = 6,02 × 10^22/6,02 × 10^23

= 0,1 mol

-----------------------------------------------

2. N = 3,01 × 10^24

N = n × L

3,01 × 10^24 = n × 6,02 × 10^23

n = 3,01 × 10^24/6,02 × 10^23

= 5 mol

---------------------------------------------

3. N = 3,01 × 10^23

N = n × L

3,01 × 10^23 = n × 6,02 × 10^23

n = 3,01 × 10^23/6,02 × 10^23

= 0,5 mol
