1) what is the mass of 1 mole of Sulfur?
2) How many moles of Silver will be formed from 15 moles AgNO3?
Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag
1) what is the atomic mass of Sulfur.
2) It appears the same number of moles Silver come from Silver nitrate. Look at the coefficents.
To find the mass of 1 mole of sulfur, you should refer to the periodic table. The atomic mass of sulfur (S) is approximately 32.06 g/mol.
To calculate the number of moles of silver (Ag) formed from 15 moles of silver nitrate (AgNO3) in the given chemical equation, you should look at the stoichiometry of the equation.
The balanced equation shows that 2 moles of silver nitrate (AgNO3) react to form 2 moles of silver (Ag). Therefore, the ratio between the moles of AgNO3 and Ag is 1:1.
So, if you have 15 moles of AgNO3, you will also have 15 moles of Ag formed.
