Which of the following values represents the molar mass of methane?
16.05g/mol
Styrene has the empirical formula CH. It has a molar mass of 104 g. What is the multiplier to get the molecular formula?
This is 8; the chemical formula is C6H5CH=CH2 and the molar mass is 104,15 g.
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
The mass of a mole of a substance expressed in grams is called a?
molacular mass
What is the molar weight of methane?
16.0425g/mole

What is the percentage by mass of different elements in methane?
Methane is composed of only carbon (C) and hydrogen (H). It has the formula of CH4. Total molar mass = 12 + 4 = 16.Mass % Carbon = 12/16 (x100%) = 75% Mass % Hydrogen = 4/16 (x100%) = 25%
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.

What is the molar weight of methane?
16.0425g/mole
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
The mass of a hydrogen atom is 1.0 amu and the mass of a carbon atom is 12.0 amu What is the molar mass of methane CH4?
12.0 + (4.00000... X 1.0) = 16.0, to the justified number of significant digits.
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
