Thus, the mass of methane is 32g.
What is the mass of 2.00 moles of O?
Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..
How many moles are there in 2g of methane?
The chemical formula of methane is CH4. We know the measured mass is 2 g. BUT we need to keep significant figures in mind. Since the measured value (2 g) only has one significant figure, the answer would be rounded to 0.1 mol.
What is the mass of one mole of methane?
One mole of methane equals 16.04 grams because a molecule of methane has an atomic weight of 16.04.
What is the molecular mass of O?
The answer is 16.04246. We assume you are converting between grams Methane and mole. You can view more details on each measurement unit: molecular weight of Methane or mol The molecular formula for Methane is CH4.
How many moles are in methane?
For example the atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore the molar mass of methane is 16g. We say that one mole of methane has a mass of 16 g, and that there are 6.022 x 1023 atoms in that mass of methane.
What is the molar mass of fe2o3?
How many molecules are in 2 moles of methane?
In your case, a mole of methane represents a collection of methane molecules. More specifically, a mole of methane contains 6.022⋅1023 molecules of methane – this is known as Avogadro’s number.
How many moles are in 1 gram of methane?
An amount of any substance in grams that is numerically equal to its atomic or molecular weight in amu has been defined as one mole of that substance. By this definition, one mole of hydrogen is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams.
Which of the following is correct for 1 mole methane?
1 mole of CH4 contains 4×6.023×1023=2.408×1024 atoms of hydrogen atoms and 6.023×1023 atoms of carbon atoms.
What is the molar mass of methane CH4 Brainly?
A. What is the molar mass of methane? One carbon atom + 4 hydrogen atoms = 12.0108 + 4(1.0079) = 16.0424 g/mol B.
