There are 0.75 moles in it.You have to devide 12 by molecular mass
First, determine molar mass of CH4:
C:12g/mol + 4x H:1g/mol=
16g/mol
Then divide by the number of grams.
64g/(16g/mol)= 4 moles of CH4
1 mole CH4 (1 mole carbon/4 moles hydrogen)(12.01 grams/1 mole carbon)
= 3.0025 grams ( to be exact, 3 is most likely the answer )
2.3 grams CH4 (1 mole CH4/16.042 grams)
= 0.14 moles methane
================
10 g of CH4 is equal to 0,625 moles.
Approx 0.62 moles.
The solubility of potassium permanganate in water at 2o 0C is 64 g/l (or 32 g/0,5 L).The molar mass of KMnO4 is 158,034 g and 0,35 moles KMnO4 is equal to 55,312 g.So it is not possible to dissolve o,35 moles KMnO4 in 0,5 L.
64 centimeters = 25.1968504 inches.
Well, think about it. There are 64 codons so there must be 64 anticodons
64 meters = 209.97 feet.
There are 5280 feet in one mile. Therefore, there are 5280 / 64 = 82.5 times 64 feet in one mile.
First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
.75 moles times 64 grams/mols = 48 grams
Four times the atomic weight of carbon plus sixteen times the atomic weight of hydrogen = about 64 grams.
four moles. Approximately. Oxygen has a molecular weight of 16.0 grams per mole so 64 grams divided by 16.0 grams per mole is four moles.
64 moles of chlorine atoms would be 64 x 35.5 grams, i.e. 2272 grams. If you meant the substance chlorine, which consists of Cl2 molecules, it would be 4544 grams.
The answer is 2 moles.
4.80 grams O2 (1 mole O2/32 grams ) = 0.150 moles of O2
The number of moles in exactly 64 grams of oxygen (O2) is two.
1+7+(8x3) =32 =32x2 (2 moles) =64
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
You have to use the equationnumber of moles = mass/Molar massn = 5/(39.1+32.1+64)n = 5/135.2number of moles = 0.04:)
22 grams carbon dioxide (0.5 moles)
