What is the atomic mass in grams of 0.35 moles of CH4?

Answer 1

I think you are asking for the mass of 0.35 moles of methane (CH4). First, we find the molecular mass of methane by addin the masses of all of the atoms. A carbon is 12, and each H is 1, so the molecular mass of CH4 is 16g/mole.

Now we multiply 0.35 moles by 16 g/mole. The moles cancel out, and we have 5.6 g.

Answer 2

First you have to find the molar mass of NH3. You do this by looking at the period table of elements and adding the molar mass of 1 nitrogen atom and the molar mass of THREE hydrogen atoms together.

This combined molar mass will have units of Grams per Mole. To get grams, all you have to do is multiply this number by 0.250 moles.

Answer 3

0.250 * (12.00 + 4*1.008) = 4.008 = 4.01 gram

Answer 4

Multiply 8 by molecular mass 16.So the answer is 128g

Answer 5

The molar mass of CH4 (methane) is 16.05 g/mol. Multiply the molar mass by the number of moles to find the Atomic Mass: 16.05 g/mol x 0.35 mol = 5.62 g of CH4.
