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

You would multiply the number of grams x Avogadro's number=number of molecules: (21.6g) X (6.022x10^23)= 1.301x10^25 molecules


How many molecules of H2O and CO2 can be made from 4 molecules of CH4 and excess O2?

The balanced equation for the combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2O4 molecules of CH4 will produce 4 molecules of CO2 and 8 molecules of H2O


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

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


How many hydrogen atoms are in 1.25 grams of CH4?

1,25 grams of CH4 contain 0,156696.10e23 atoms.


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


How many moles of CH4 are in 200 grams of CH4?

200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4


How many mole of CH4 are in 96.0 grams of CH4?

Divide 96 by molecular mass.So the answer is 6mol


How many molecules in 10 grams of methane?

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 CH4 are in 2.52 mol of CH4?

Divide 2.52 by molecular mass 16.Then multiply by avagadro constant


What pair of molecules has the strongest dipole - dipole interactions co2-co2 or co2-ch4 or nh3-nh3 or nh3-ch4 or ch4-ch4.?

nh3-nh3 because they are both polar molecules


How many grams of CO2 are formed for every gram of CH4 that combusts?

The balanced equation for combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2OThus, one mole CH4 produces 1 mole CO21 g CH4 x 1 mole CH4/16 g = 0.0625 moles CH40.0625 moles CH4 ==> 0.0625 moles CO20.0625 moles CO2 x 44 g CO2/mole = 2.75 g CO2Thus, the answer would be that 1 grams of CH4 will produce 2.75 grams of CO2 after complete combustion.
