Question

How many electrons that may bank in 1.6 g of methane

Answer 1

6.02 × 10^23

Step-by-step explanation:

Number of moles of methane = 1.6/16 = 0.1

In one mole there are 6.02 × 10^23 atoms

Thus, in 0.1 mole there are 0.1 ×6.02 × 10^23 atoms =6.02 × 10^22 atoms

Hence total number of electrons = number of electrons present in CH4 × atoms present in 0.1 mole.

=10×6.02 × 10^22 =6.02 × 10^23

Answer 2

6.022 x 10^23

Step-by-step explanation:

There are 6.022 x 10^23 electrons that may bank in 1.6 g of methane.

10×6.023×10²²

6.023 ×10²³
