∙ 8y ago1 C = 1 x 12.01 (mass of carbon) = 12.01 g/mol
4 H = 4 x 1.008 (mass of hydrogen) = 4.032 g/mol
12.01 g/mol C + 4.032 g/mol H = 16.042 g/mol CH4
hope that helped

How many moles of CH4 are present in 6.07 g of (CH4)?
Divide 96 by molecular mass.So the answer is 6mol
How many moles of oxygen will be needed to completely oxidize 64g CH4?
Molar mass:O2 32 g/molCH4 16 g/molReaction:CH4 + 2 O2 --> CO2 + 2H2OCalculus1 mol CH4 with 2 moles O2Given: 24 g CH4 equals 24/16 = 1.5 mol CH4this will need 2 * 1.5 moles O2 = 3.0 mol O23.0 mol O2 equals 3.0 * 32 = 96 g O2
How many molecules are in a 2.0 moles of CH4?
CH4 + 2 H2O = 3 H2 + CO2 8 moles CH4 produce 8 x 3 moles H2, which is 24.
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
What mass of water is produced from the complete combustion of 2.50x10-3 of methane?
Methane is CH4. Combustion is CH4 + 2O2 ==> CO2 + 2H2O1 mole CH4 produces 2 moles H2Omoles CH4 used = 1.1x10^-3 g x 1 mole/16 g = 6.875x10^-5 molesmoles H2O produced = 6.875x10^-5 moles CH4 x 2 moles H2O/mole CH4 = 1.375x10^-4 molesmass H2O produced = 1.375x10^-4 moles x 18 g/mole = 2.475x10^-3 g = 2.48 mg (3 sig.figs)

Are there two moles in CH4?
That's a tricky question, because one molecule of CH4 is simply that, one atom of carbon and 4 atoms of Hydrogen. Moles are a UNIT used to transform atoms (which we cannot measure individually in the lab) into practical units such as grams (which we can measure). The moles of CH4 depend on the mass, in SI units of grams, that you have of this substance. The molecular weight of CH4 is 16 g/mol (12 for Carbon + 1 for each Hydrogen). If you WANTED 2 moles of CH4, you need to multiply this molecular weight by 2 moles to get 32 grams (the moles cancel out upon multiplication). So, 32 grams of CH4 is 2 moles of CH4.
How many moles in 64 grams of CH4?
There are 0.75 moles in it.You have to devide 12 by molecular mass

What mass of CO2 is produced in the reaction of 4 moles of CH4 in excess O2?
Mass of 4 mole CO2 , this is 4 * (12 + 2*16) = 176 grams
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 molecules are in a 2.0 moles of CH4?
CH4 + 2 H2O = 3 H2 + CO2 8 moles CH4 produce 8 x 3 moles H2, which is 24.
How many moles 64 grams of ch4?
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
