It is just as the number.It has 6.5 moles in it
Simply divide it by 6.022 × 10 23.You can get the answer. 112.09mol
4.66715966 × 1024
It depends on temperature,pressure and volume.THese are needed to find number of moles
Balanced equation. CH4 + 2O2 -> CO2 + 2H2O one to one, but set-up anyway and limiting reacting known 2.0 moles CH4 (1 mole CO2/1 mole CH4) = 2.0 moles CO2 produced ( by the way, those numbers are subscripts, not superscripts )

That depends on the conditions the CH4 is subjected to. At STP, CH4 would be a gas with 22.4 liters/mole (0.0224 m3/mole) or 44.6 moles/m3. If you have it at cryogenic temperatures and high pressures like the atmosphere of Jupiter, the density will be different.
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
In 3 moles of CH4, there are 18.06 x 10^23 times Hydrogen atoms.

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.
2,8 moles is of course equivalent to 2,8 moles !Probable is a spelling error in your question.

There are 0.75 moles in it.You have to devide 12 by molecular mass
CH4 + 2 H2O = 3 H2 + CO2 8 moles CH4 produce 8 x 3 moles H2, which is 24.
CO2 + 4H2 --> CH4 + 2H2O0.500 moles CO2 (1 mole CH4/1 mole CO2) = 0.500 moles CH40.500 moles CO2 (2 moles H2O/1 mole CO2) = 1.00 moles H2O-------------------------------------------------------------------------------------add= 1.50 moles total product====================
One molecule has four H atoms.So two moles have 8 moles
0.86 moles CH4 (4 mole H/1 mole CH4)(6.022 X 10^23/1 mole H) = 2.1 X 10^24 atoms of hydrogen --------------------------------------------
First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
