Use a calculator. I would walk you through it, but it should be simple.
<span>the balanced net ionic equation for the precipitate reaction
</span>
Na2SO4 + Ba(NO3)2 -------------> <span>BaSO4 + Na2(NO3)2
</span><span>the number of moles of sulfate in the sample
M = m /n
M molar mass
m mass
n number of moles
so n =m/M
n = 8.642/233.33=0.037mol

Answer:
C) 8
Step-by-step explanation:
The Distributive property says a(b+c)=ab+ac, using this knowledge, follow the steps provided below to solve the problem :)
1) Distribute -5 to a and 3:
-5a-15=-55
2) Add 15 to both sides:
-5a=-40
3) Divide both sides by -5:
a=8
