What ratio is used to carry out each conversion? a.mol ch4 to grams ch4 b.l ch4(g)

Explanation:

According to mole concept

a. Moles to grams

Number of moles =

Mass of = Moles of 16 g/mol

b. Liters to moles at STP.

At STP,1 mol gas occupies 22.4 L of volume.

Multiply the given volume of gas in L with

c.Molecules of to moles

1 mole = atoms or molecules

So, in 1 molecule = mole.

Multiply the given number of molecules with mole to get the number of moles of .

0.36 atm is the correct answer.
