How many grams are in 5.2 moles of magnesium sulfide?
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
How many moles are in 56 micrograms of selenium?
The molecular mass of selenium is 78.96g/mol. You need to convert micrograms to grams. i.e. 56/1,000,000 is 0.000056 grams. 0.000056/78.96 is 0.00000071 moles.
How many grams of koh are needed to prepare 250 milliliters of a 2 m solution of koh formula mass 56?
28 gram. = 2 * 56 * 250 / 1000
Calculate the mass of butane needed to produce 96.3 of carbon dioxide?
2C4H10(g) + 13O2(g) ---> 8CO2(g) + 10H2O(g)Now, 96.3 grams(?) of carbon dioxide would be:m=96.3 n=m/MM=44.01 = (96.3)/(44.01)n=? = 2.19Now, the molar ration of butane:carbon dioxide1/4n(CO2) =n(C4H10)= .55 molfor butane:m=? m = nMM=58.24 = 31.86g butanen=.55
Iron-56 mass number?
Iron is a metal element. Atomic mass of it is 56.
What is the percentage of Fe in iron ammonium sulfate hexahydrate?
14% FeThe formula for iron ammonium sulfate hexahydrate is (NH4)2Fe(SO4)2·6H2O, which can also be written as FeH20N2O14S2.To determine the percentage of Fe in the compound, divide the mass of Fe by the mass of the compound and multiply by 100. The molar mass of Fe is 56 g/mol. The molar mass of the compound is 392 g/mol. There is only one Fe atom in the formula, so the mass of Fe is 56 g/mol.%Fe = (56 g/mol)/(392 g/mol) x 100 = 14%
