Answer:
3.1695 moles
Explanation:
Moles × grams/1 mole = x amount of grams
Grams: 1 mole/grams
2AgNO3 + Ni2+ = Ni(NO3)2 + 2Ag<span>+</span>
From the reaction,
it can be seen that AgNO3 and Ni2+ has following amount of substance
relationshep:
n(AgNO3):n(Ni)=2:1
From the relationshep we can determinate requred moles of Ni2+:
n(AgNO3)=m/M= 15.5/169.87=0.09 moles
So, n (Ni)=n(AgNO3)/2=0.045 moles
Finaly needed mass of Ni2+ is:
m(Ni2+)=nxM=0,045x58.7=2.64g
Answer:
t? im pretty sure have a good day
Plug in any number that yo think it’s the answer and make a t chart and put every letter in it and the other side the number until it is balanced
