7.71 grams sulfur (1 mole S/32.07 grams)
= 0.2404 moles of sulfur
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
Hydrogen reacts with sulfur in the proportions dictated by this equation:H2 + S --> H2S. The reactants are in a 1:1 proportion with each other, so 1.72 moles of hydrogen will react with 1.72 moles of sulfur.
Oxidation-reduction reaction:Ag^+(aq) + Al(s) ===> Ag(s) + Al^3+ or looked at another way... 3AgNO3(aq) + Al(s) ===> Al(NO3)3(aq) + 3Ag(s) moles AgNO3 present = 92.8 g x 1 mole/170 g =0.546 moles moles Al present = 1.34 g x 1 mole/26.9 g = 0.0498 moles Al is limiting based on mole ratio of 3 AgNO3 : 1 Al moles Ag(s) produced = 0.0498 moles Al x 3 moles Ag/mole Al = 0.1494 moles Ag mass of Ag = 0.1494 moles Ag x 108 g/mole = 16.1 g Ag formed
There are 0.660 moles of sulfur atoms in 0.660 moles of S. To find the number of atoms, you would multiply the number of moles by Avogadro's number (6.022 x 10^23), so there are 3.97 x 10^23 sulfur atoms present.
To find the number of moles of S in 22.9 g of C6H10S, you need to first calculate the molar mass of C6H10S, which is 126.23 g/mol. Then, divide the given mass by the molar mass to find the number of moles. For S in C6H10S, the molar mass contribution is 32.06 g/mol, so 22.9 g is equivalent to 0.717 moles of S.
1 g of ammonia (NH3) is equal to 0,059 mol.
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
6,5 grams of sulfur S are equal to 0,203 moles.
Hydrogen reacts with sulfur in the proportions dictated by this equation:H2 + S --> H2S. The reactants are in a 1:1 proportion with each other, so 1.72 moles of hydrogen will react with 1.72 moles of sulfur.

After 3 moles of S have reacted, 3 moles of F2 will also have reacted since the reaction ratio is 1:1 based on the balanced chemical equation. This leaves 6 moles of F2 remaining (9 moles initially - 3 moles reacted).
There are 0.660 moles of sulfur atoms in 0.660 moles of S. To find the number of atoms, you would multiply the number of moles by Avogadro's number (6.022 x 10^23), so there are 3.97 x 10^23 sulfur atoms present.

Then, divide the given mass by the molar mass to find the number of moles. For S in C6H10S, the molar mass contribution is 32.06 g/mol, so 22.9 g is equivalent to 0.717 moles of S.
the atomic mass of FeS2 is 110. You cannot find the no. of moles in a mole of FeS2 coz it is only a mole.
To determine the number of atoms in 8g of sulfur (S), you would first calculate the number of moles using the molar mass of sulfur (32 g/mol). Then, using Avogadro's number (6.022 x 10^23), you can convert the moles to atoms.
Cu(s) + 2AgNO3(aq) ---> Cu(NO3)2(aq) + 2Ag(s) So you need half as many moles of Cu. Thus 5.8/2 = 2.9 moles of Cu are needed.
