How many molecules of ch4 are in 48.2g of theis compound?

1 mol of any substance is made of 6.022 x 10²³ units. These units could be atoms making up elements or molecules making up compounds. methane is CH₄, 1 mol of CH₄ is made of 6.022 x 10²³ molecules of methanemolar mass of CH₄ is 16 g/mol so 16 g of CH₄ is made of 6.022 x 10²³ CH₄ moleculestherefore 48.2 g of this compound is made of – 6.022 x 10²³ /16 x 48.2 = 1.81 x 10²⁴ molecules of methane there are 1.81 x 10²⁴ molecules of methane

i’m pretty sure its b i might be wrong though!

the answers would be the first one and the second one
