Find out the percentage of hydrogen in the molar mass of methane.

Molar mass of CH4:

C = 1 * 12.01 g = 12.01 g

H = 4 * 1.01 g = 4.04 g

Total = 16.05 g

4.04 g/16.05 g * 100% = 25.171%

0.25171 * 20 g = 5.0342 g

There are about 5.03 grams of hydrogen in 20 grams of methane gas.

How many molecules of methane are in .123 moles of methane?

There are approximately 4.68 x 10^22 molecules of methane in 0.123 moles of methane. This is calculated using Avogadro's number, which is 6.022 x 10^23 molecules per mole.


How many molecules are in 30 liters of methane (CH4) at STP?

At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 liters. So, in 30 liters of methane, there would be 30/22.4 = 1.3393 moles. One mole of methane contains 6.022 x 10^23 molecules, therefore 30 liters of methane at STP would contain 1.3393 * 6.022 x 10^23 = 8.07 x 10^23 molecules.


What are the steps needed to convert 77.2 grams of methane to molecules of methane. Please wrote them out ( indluding tchart)?

Step1: Find molar mass of methane, CH4. C=12; H=1; 12+1+1+1+1 = 16 g/moleStep2: Convert grams to moles. 77.2 g x 1 mole/16 g = 4.825 moles methaneStep3: Convert moles to molecules using Avogadro's number.4.825 moles x 6.02x10^23 molecules/mole = 2.90x10^24 moleculesUnfortunately, I don't know what a tchart is, so I didn't include it.


Calculate the number of molecules given grams i.e how many molecules are there in 21.6 grams of CH4?

To calculate the number of molecules in 21.6 grams of CH4, you need to first determine the molar mass of CH4 (methane). The molar mass of CH4 is approximately 16 g/mol. Next, divide the given mass (21.6 g) by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.


How many atoms are there in 64.5 grams of methane?

Molecular mass of CH4 = 12.0 + 4(1.0) = 16.0 Amount of CH4 = 64.5/16.0 = 4.03mol 1mol of CH4 contains 6.02 x 1023 molecules (avogadro constant). Therefore 4.03mol of CH4 contains 4.03 x 6.02 x 1023 = 2.43 x 1024 molecules.

How many methane molecules of Ch4 have a mass equal to 3.20 grams?

One mole is equal to 6.022 x 1023 of anything. In this case, we are looking for molecules. So 1 mole=6.022 x 1023 molecules. We have 2.3 moles, so we want to know how many molecules are there. 2.3 mol CH4 x 6.022x1023 molecules CH4 / mol CH4 = 1.38x1024 molecules of CH4
