How many molecules of ch4 are in 48.2 g of this compound? a) 2.00 x 1023 b) 5.00 x 10-24 c)1.81 x 1024 d) 4.00 e) 4.64 x 1026 10) -

The correct answer is Option C.

Explanation:

To calculate the number of moles, we use the equation:

Given mass of methane = 48.2 g

Molar mass of methane = 16 g/mol

Putting values in above equation, we get:

According to mole concept:

1 mole of compound contains number of molecules.

So, 3.0125 moles of methane will contain = number of molecules.

Hence, the correct answer is Option C.

the answer is the
