The concentration of alumina in the ore is necessary; also the effective yield.
The molar mass of benzonitrile is 103,12 g .
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
The molar mass of Al2O3 is 101.96 g/mol. To calculate the mass of 9.27 moles of Al2O3, you would multiply the moles by the molar mass: 9.27 mol x 101.96 g/mol = 945.442 g. So, the mass of 9.27 moles of Al2O3 is approximately 945.442 grams.
You divide the 6.073 by 6.022x1023 (avagadros number) to get the moles, then multiply by molecular mass (18) to get mass in grams
5.0 grams CO2 (1mol CO2/44.01g) = 0.11 moles CO2
Mass = moles x formula mass Mass = 0.139 x atomic mass of copper (63.5) Mass = 8.83g
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
Calculate the mass in grams of water vapor produced if 3.11 moles of propane is burned
balance your chemical reaction equation then calculate moles, then calculate weight.
well take sodium, which the molar mass is 23.0 g/mol and multiply by # of moles (4) and you get 92g
To calculate the number of moles from grams, you must divide by the substance's molar mass
The molar mass of benzonitrile is 103,12 g .
The maximal mass is 30 moles sulfur dioxide.
The results of a titration will tell you the number of moles present in the analyte. If you then also know the mass of this analyte, you can calculate the molecular weight as mass/moles.
Mass-mass problems can be solved in various ways. You should start by writing a balanced equation for chemical reaction involved and eventually change the mass into moles which will facilitate the comparison and allow you to calculate the number of moles required.
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
1 mole of Copper has a mass of 63.546 g. So, 14.5 moles will be 14.5 times that amount. Do the math.
