Question

The number of electrons in 1.6 g of CH 4

Answer 1

HEY YOUR ANSWER IS .....



MW of methane = 16 g/mole

 

So, no of moles of methane in 1.6 g = 1.6 /16 g/mole = 0.1

Since, in 1 mole methane there are 6.022 x 1023 molecules of methane, 

 therefore , in 0.1 mole there will be 0.1 x 6.022 x 1023 molecules of methane

In 1 methane molecule there are 10 electrons (6 + 4)

so , total electrons in 0.1 mole or 1.6 g = 10 x 0.1 x 6.022 x 1023 

= 6.022 x 1023 

Answer 2

o, no of moles of methane in 1.6 g = 1.6 /16 g/mole = 0.1. Since, in 1 mole methane there are 6.022 x 1023 molecules of methane, so, in 0.1 mole there will be 0.1 x 6.022 x 1023 molecules of methane.
