The answer is 0,253 moles.
First you need the molar mass of citric acid. It is 192 g/mol. Now you can calculate the number of moles: 0.1 g x (1 mol/192 g) = 0.00052 mol
3,80 g Zn have 0,058 moles.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.
573,28 of g of AgCI is equivalent to 4 moles.
48,5 g sample of CS2 is the equivalent of 0,637 moles.
First you need the molar mass of citric acid. It is 192 g/mol. Now you can calculate the number of moles: 0.1 g x (1 mol/192 g) = 0.00052 mol
First determine the balanced chemical reaction:4Al + 3O2 ---> 2Al2O3Next figure out the number of moles of oxygen you start with by dividing 192 by the molecular weight of oxygen (16 g/mol). Then use the coefficients from the reaction to determine how many moles of Al would need to react with the oxygen to convert all the oxygen and aluminum to aluminum oxide.192 g * (1 mol O / 16 g O) * (4 moles of Al/6 moles of O) = 8 mol of AlFinally multiply by the molecular weight of Aluminum to figure out the mass:8 mol Al * (27 g/mol) = 216 g of Al
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.
The answer is 0,4 moles.
978 g calcium contain 24,4 moles.
14,84 g magnesium are equivalent to 0,61 moles.
573,28 of g of AgCI is equivalent to 4 moles.
573,28 of g of AgCI is equivalent to 4 moles.
