Sorry I meant 12:25 is the answer.

You must make a common denominator. 1. Find the lcm of the denominators 2. Multiply the denominator by the number that makes it the lcm (ex. 2/3 plus 2/4 lcm o 3 and 4 is 12. 3x4= 12. 4x3=12) 3. add them up!

it is based on the placement of the element on the periodic table

Na is +1 and is the cation and PO4- is a polyatomic ion and the anion the placement always goes to your noble gases in column VIIIA (18)

what are you solving for? pH or H+

total you have 3 Na ions and 1 PO4- ions...so all together 4 ions

If I did it correctly is should be 110 g Zn

I don't know then...unless it is separating out each element...then it will have Na=3 P=1 and O=4...then it would be your 3 anions and 5 cations
