How many grams of methane gas CH4 are contained in a volume of 144 liters at STP?
One mole has amass of 16g.There are 6.428mol.Its mass is 102.85g
How many molecules of oxygen 2 are needed to react with which molecule of methane CH4?
6 molecules of oxygen are needed to react with 3 methane molecules as one molecule of oxygen ( O2) are needed for methane gas.
How many hydrogen atoms are there in 3.50 grams of methane?
3.5 g CH4 x 1 mole/16 g x 6.02x10^23 molecules/mole x 4 H atoms/molecule = answer.
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
What is the mass of 0.2 moles of methane?
16 grams per mole. Methane is CH4. Look at the Periodic table: Carbon is 12 grams/mole and Hydrogen is 1 gram/mole, so 1*12 + 4*1 = 16.
How many H2O molecules are contained in 1 mole?
Because they are.
How many molecule's of carbon there are in 2.50 molecule's of methane?
Moles of methane. No half molecules, I think! 2.50 moles methane (1 mole C/1 mole CH4)(6.022 X 1023/1 mole C) = 1.51 X 1024 molecules of carbon --------------------------------------------
How many molecules are contained in 1 mole of water?
This is the number of Avogadro: 6,022 140 857(74).10e23.
How many grams of methane gas CH4 are contained in a volume of 144 liters at STP?
One mole has amass of 16g.There are 6.428mol.Its mass is 102.85g
How many atoms are present in a mole of methane?
Each molecule of methane contains one carbon atom, as shown by the formula for methane, CH4. Therefore, the number of carbon atoms in one mole of methane is the same as Avogadro's Number, about 6.022 X 1023.
How many molecules of oxygen 2 are needed to react with which molecule of methane CH4?
6 molecules of oxygen are needed to react with 3 methane molecules as one molecule of oxygen ( O2) are needed for methane gas.
How many moles of chlorine gas are contained in 9.02 x 1023 molecules?
9.02*1023 (molecules) divided by 6.022*1023 (molecules per mole) = 1.5 moles of ANY thing
How many hydrogen atoms are there in 3.50 grams of methane?
3.5 g CH4 x 1 mole/16 g x 6.02x10^23 molecules/mole x 4 H atoms/molecule = answer.

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 water molecules in 1.50 mole of water?
1.5 mole H2O x 6.02x10^23 molecules/mole = 9.03x10^23 molecules
How many ammonia molecules are in a mole of ammonia?
There are 6.02x10^23 molecules in one mole of anything.
How many atoms are in one mole of methane?
3.01X10 24
