Question

how+many+atoms+and+molecules+are+present+in+1.6+grams+of+methane

Answer 1

Answer:

Explanation:

Let’s think this through: 1.6 grams of methane, is some number of moles of methane. Methane is CH4, meaning it contains one carbon atom and four hydrogen atoms per molecule. One mole of carbon is 12 grams and one mole of hydrogen is 1 gram. CH4 is therefore 16 grams per mole

Now that we have this, we can say:

Given Mass / Gram-Formula Mass = # of Moles

1.6 grams / 16 grams = 0.1 moles of CH4
