25.0 ml of 15% NH4NO3 solution is diluted to 300.0 ml. What is the concentration of the diluted solution?
My Work:
Total molar mass of NH4CO3 = 80.052
.15 x 80.052= 12.0078
25.0 ml (12.00 M) = 300.0 ml (c2)
300.19/300.0ml =
The concentration is = 1.0M

I don't agree.
Why did you convert from % to M? I don't think you can convert to M without knowing the density.
I would keep it in % and use
15 x 25.0 = % * 300
% = ?
Or another way, you are diluting it by a factor of 300/25 or 12 times.
So 15%/12 = ?%

whoops I took 15% of the molar mass of NH4NO3
So .15 x 25=3.75
3.75 x 300= 1125 ?
So .15 x 25=3.75
3.75 x 300= 1125 ?
