Question

Calculate the number of electrons present in 1.6 grams of CH4.

Answer 1

Answer:

One mole is 6.02 * 10^23 entities. Because carbon atoms have 6 electrons, we must know how many electrons are in 6.02 * 10^22 carbon atoms. This would be (6.02*6)* 10^22 = 36.12 * 10^22 electrons.

Answer 2

Answer:

6.022×10²³

Explanation:

16 g CH4 has 6.022×10²³ molecules of CH4

1.6 g CH4 has 6.022×10²³ ×1.6/16molecules of CH4 =6.022×10²³/10 molecules

so, 1 molecule of CH4 has 10 electron

6.022×10²³/10 molecules have

6.022×10²³×10/10

=6.022*10²³ electrons
