How many moles 0.170g C?
The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.
What is the molar mass of C6Cl6?
mass of 6 moles of C = 12X6 =72g mass of 6 moles of Cl = 35.5X6 = 213g mass of 1 mole of C6Cl6 = 285g
How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
Formula for moles?
number of moles = mass of the material/molar mass
What is the mass of 1.23 moles of iron?
The mass of 1.23 moles of iron is 58,69 g.
How many moles 0.170g C?
The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.
If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the?
Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
What is the molar mass of C6Cl6?
mass of 6 moles of C = 12X6 =72g mass of 6 moles of Cl = 35.5X6 = 213g mass of 1 mole of C6Cl6 = 285g
How many moles of aluminum are present in 856g of aluminum sample?
Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
What is the mass in grams of 3.41x10e26 molecules of water?
first you divide by avagadro's number to get the number of moles. 3.41x10^26 / 6.022x10^23 = 566.25 moles The molecular mass of water is 18. moles is mass/molecular weight so moles by the mass is the weight. 566.25*18 is 10192.63g. This is 10.193kg. Are you sure your molecule count was not exponentially lower?
How many moles of C are in 90g of CO2?
Divide mass (g) by molar mass (g/mol) : 30 g C2H2 = 30/26 g 35 g H2O = 35/18 g
How many moles of acetic acid C H3COOH a re contained within 21.71g of acetic acid?
Molar mass of ethanoic acid = (1x12) + (3x1) + (1x12) + (2x16) + (1x1) = 60 no. of moles = mass/ molar mass = 21.71/60 = 0.362 moles
How many moles is 3 grams of carbon?
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. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.
How many moles are in 48g of carbon?
To determine this we must first know what the molar mass of Carbon is and that equals 12.01g. This mean for every 12.01g of Carbon, we have one mole. Therefore:48gC x (1 mole C/ 12.01g C) = 3.99 molesRounded off, in 48g of Carbon there are about 4 moles.
How many moles of CCL4 are there in 56 grams?
Divide the Molar Mass of C and Cl4 by 56 to get your awnswer!
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
