Find the mass of Ag around the Nickel pole

In summary, the mass of Ag put around the Nickel pole in an AgNO3 solution with volume 50ml and concentration 0.1 mol/litre until the concentration is 0.02 mole/litre is 0.432 grams. This is calculated by subtracting the number of moles of Ag at the beginning (0.005 moles) from the number of moles at the end (0.001 moles), resulting in 0.004 moles of Ag, which is then multiplied by the molar mass of Ag (108 g/mol) to get the final mass of 0.432 grams.

Homework Statement


A nickel pole is put in an AgNO3 solution with volume 50ml and concentration 0.1 mol/litre until the concrentration is 0.02 mole/litre. Find the mass of Ag that is put around the Nickel pole.

Homework Equations


2AgNo3+Ni->Ni(NO3)2+2Ag
number of moles= concrentration*volume
n1=0.1*0.05=0.005 moles
n2=0.02*0.05=0.001 moles.
n1-n2=0.004 moles.
So the numebr of Ag moles will be 0.004 too

The Attempt at a Solution


n1=0.1*0.05=0.005 moles
n2=0.02*0.05=0.001 moles.
n1-n2=0.004 moles.
So the number of Ag moles will be 0.004 too
Then m=0.004*108=0.432 moles. Am I right?

Grams, not moles. Other than that what you did looks OK.
