What mass of CO2 is produced in the reaction of 4 moles of CH4 in excess O2?
For every 1 mole of CH4 that reacts, 1 mole of CO2 is produced. Therefore, 4 moles of CH4 will produce 4 moles of CO2. To calculate the mass of CO2 produced, you would need to multiply the moles of CO2 by its molar mass (44 g/mole) to get the total mass produced.
What would have the greatest mass 1 mole of iron atoms 2 moles of oxygen atoms 4 moles of carbon atoms or 1 mole of potassium atoms?
1 mole of iron atoms has the greatest mass - 55,845 g.
What is the approx mass of one mole of helium atoms?
4 grams. Approximately, mass (in grams) of 1 mole of any chemical element is just the atomic mass of this element (4 - for He, 12 - for C, and so on). It follows from the definition of one mole - number of atoms in 12 g of C.
How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
What is the mass in grams of 4.3x1016 atoms He?
4.3x10^16 atoms He x 1 mole He/6.02x10^23 atoms x 4 g/mole He = answer (do the math)

What is the mass of one mole atoms?
The mass of one mole of atoms is equal to the atomic mass of the element expressed in grams. This is known as the molar mass. For example, the molar mass of carbon (C) is 12 grams per mole, of oxygen (O) is 16 grams per mole, and so on.
What is the mass in grams of 4.3x1016 atoms He?
4.3x10^16 atoms He x 1 mole He/6.02x10^23 atoms x 4 g/mole He = answer (do the math)
How many moles in 6.071grams of helium?
To find the number of moles in 6.071 grams of helium, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 grams per mole. Therefore, 6.071 grams / 4 grams/mol ≈ 1.52 moles of helium.
What is the mass of 0.2 moles of methane?
16 grams per mole. Methane is CH4. Look at the Periodic table: Carbon is 12 grams/mole and Hydrogen is 1 gram/mole, so 1*12 + 4*1 = 16.
What is the molecular mass of hydrogen?
For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.eThis means that 1.00000 mole H2 has a mass of 2.01588 grams
What is the mass of 1.5 moles of helium atoms?
1 mole of He-4 isotope weight about 4 g So 1.5 mole of He-4 isotope weight about 6 g
What is the mass of helium?
helium = 4 molar mass
What is the mass of six helium atoms?
32 g
