:D thankyou very much for explaining it all, it seems i was treating the 0.2^1/2 as 0.2*0.5 (being half of one...so wrong!). To get 0.4472 though, 0.2 needs *2.236, it dawned to me as 2.24, bringing so3 to 62.4g after rounding. I promise to practice my algebra. I appreciate yo...

I thought so2 would be 0.4, I didn't have so3 correct on my ice table. I get x as 0.485; 0.471(x-0.4)=(0.4)(0.2)^1/2 0.471x-0.1884=0.04 0.471x=0.2284 But x needs to be 1.18 for so3 to be 0.78M(1.18 - 0.4) to multiply with 80, am i missing something?
