Question

calculate the number of molecules in 32 g of methane​

Answer 1

Answer:

Therefore. the number of methane in 32 g sample = 32 / 16 = 2 moles.

Answer 2

Answer:

Given 32g Methane (CH4 )

molar mass= 16

Moles of CH4  =  32/16 = 2 moles

1 mole = 6.023×10²³ molecules

Then 2 moles = 6.023ˣ10²³ˣ2

                       = 12.046 ˣ 10²³ molecules

the number of molecules in 32 g of methane​ is 12.046 ˣ 10²³ molecules
