What is the molar weight of methane?
16.0425g/mole
What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
The formula for methane is CH4. Four moles of methane would have a mass of how many grams?
Taking carbon @ 12.01 g/mol & hydrogen @ 1.01 g/ mol methane has 1 carbon & 4 hydrogen, so it is:12.01g + 4(1.01g) = 16.05g per mole.For 4 moles: 4 x 16.05 g = 64.20 g
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.
What is the theoretical percentage of water of hydration in cacl2-2h20?
1. Find the molar mass of the hydrate (Calcium Chloride Dihydrate).Find the molar mass of water and the anhydrate (anhydrate + water = hydrate); add the molar mass values of each to find the molar mass of the hydrate.Molar Mass CaCl2: 110.98g+ Molar Mass H2O: 36.04g*Molar Mass CaCl2 * 2H2O: 147.01gFinding Molar Mass# atoms element A * atomic mass element A = Mass A# atoms element B * atomic mass element B = Mass B... etc.Add up all the mass values and you have the value for molar mass. Do this for both the anhydrate and the water molecules. Add these values together to find the molar mass of the hydrate.Molar Mass Anhydrate + Molar Mass Water Molecules* = Molar Mass Hydrate* Tip: the molar mass of water for all hydrate calculations is 18.02g x number of water molecules. This number may be useful to remember on the day of the test or while doing practice problems.*2. Calculate the percentage of water in hydrate.Divide the molar mass of water by the molar mass of the hydrate, and multiply result by 100%.36.04g147.01g x 100%Percent water in hydrate is 24.52%.

How does water gas compare to methane in terms of thermal energy produced?
The molar heat of combustion of methane (890 kJ/mol) is higher than that of water gas (525 kJ/mol)

What is the limiting reactant in combustion of methane is 2.8 moles of methane and 5 moles of oxygen?
Methane reacts with oxygen in the following way. CH4 + 3 O2 --> CO2 + 4 H2O. If 5 moles of oxygen react with 2.8 moles of methane, only 1.67 moles of methane would be consumed because of the molar ratio 1:3. This would produce 1.67 moles of carbon dioxide and 6.67 moles of water.

If know molar absorbance coefficient of a substance how can beer- Lambert law be used to determine the concentration of a subsatnce?
you would have to know the following values, Absorbance (A), Concentration (C), and cell length (l) and plug it into the formula A=eCl or C = A/Cl
True or false The molar enthalpy values and fusion stay the same if you were to reverse the process?
False, I'd think.
What is CH2 chemical formula with molar mass?
C2H6 is a gas (in chemistry), similar to methane, propane, and butane. I'm not sure what the name of this gas is, but it ends in -ane. Sure of that.
What is the difference between hydroge and methane?
Water is polar and has a bent shape. Methane is non-polar and is tetrahedral. These molecular-level differences help explain why, despite their similar molar masses, they have vastly different physical properties.
