The formula for methane is CH4. Four moles of methane would have a mass of how many grams?

∙ 7y ago
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

∙ 13y agoNo. of moles = Given mass of element or compound/ molar mass of element or compound.
Molar mass of Methane(CH4) = 16 g
No. of moles of Methane in 345g = 345/16=21.562 moles.

∙ 15y agoit's around 67.974g, depending on how acurate the molar mass is (mine is to three decimal places)
Wiki User
∙ 14y ago1 mole C= 12.01 g
4 moles H= 4.04 g
Therefore, 1 mole of CH4 = 12.01g + 4.04g = 16.05g

∙ 12y agomolar mass of methane is 16g/mol
so 4 mols is 64 grams

The formula for methane is CH4 Four moles of methanes would have a mass of?
Four times the atomic weight of carbon plus sixteen times the atomic weight of hydrogen = about 64 grams.
The formula for ammonia is NH3 the mass of 3 moles of ammonia would be how many grams?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
How many grams are in 2.8 moles of gold?
2.8 moles of gold would be 550g of gold. Multiplying the amount of moles by the molar mass (197.0 grams/moles) will give you the grams by cancelling out the moles units.
What is the empirical formula for a compound with the 3.1 percent hydrogen 31.5 Phosphorus and 65.4 percent oxygen?
Say you have 100 grams of the compound. If so, then you would have 3.1 grams H, 31.5 grams P, and 65.4 grams O. Convert these to moles: 3.1 grams H ÷ 1.01 grams/mol = 3.07 moles H 31.5 grams P ÷ 31.0 grams/mol = 1.02 moles P 65.4 grams O ÷ 16.0 grams/mol = 4.09 moles O Divide each of these by the smallest number, which is 1.02: 3.07 ÷ 1.02 = 3 1.02 ÷ 1.02 = 1 4.09 ÷ 1.02 = 4 These are your ratios. The empirical formula is then H3PO4
Empirical formula for a compound that contains 32.2 percent Ca and 67.8 percent N by mass?
Assume the compound has a molar mass of 100 grams, from the information given, 32.2 grams is Calcium and 67.8 grams is Nitrogen.You then find the moles of each, which would be moles of Ca and moles of N.Dividing the two moles gives you the mole fraction: which we approximate to 6. This means that for every 1 mole of Ca, there are 6 moles of N, thus the answer is

The formula for ethyl alcohol is CËÃHËÆOH The mass of 2 moles of ethyl alcohol would be grams?
The mass would be approximately 92 grams.
How many grams in 2 moles of methane?
The amount of grams in two moles depends on the element or compound that you have two moles of. For example, the molar mass of oxygen is about 16 grams. So two moles of oxygen would be about 32 grams.

224 grams of Oxygen will be in 2 moles of Potassium dichromate.
How do you calculate the molecular formula of a substance which contain 80 percent C and 20 percent H?
You can only calculate the empirical formula because you do not have a mass of this compound given. To do the empirical formula assume 100 grams and change percent to grams. Get moles. 80 grams Carbon (1 mole C/12.01 grams) = 6.66 moles C 20 grams hydrogen (1 mole H/1.008 grams) = 19.84 moles H the smallest becomes 1 in the empirical formula and the other number is divided by it, Thus; H/C 19.84 moles H/6.66 moles C = 2.9, which we call 3 so, CH3 --------------- is the empirical formula To get the molecular formula tour question needed to read; How to calculate molecular formula from such ans such mass of compound with these percentages of elements, Which, of course, your question did not provide. Then you would have divided that given mass by the mass total of the elements of the empirical formula, got a whole number by which you would have multiplied the numbers of your empirical formula to get molecular formula.
