thanks!

1.5748(0.944-1.8447Y/1.5377) + 1.90293Y = 0.953 -.4026 Y + 1.90293 Y = 0.953 1.50033 Y = 0.953 Y=.6352 1.5377 X +1.8447(.6352) = 0.944 1.5377 X +1.1717 = 0.944 1.5377 X = -.2277 X=-.148078

I see you took my advice literally about carrying extra places. It isn't necessary to use ALL of those numbers that show up on your calculator. I think 1.5377X + 1.8447Y = 0.944 will be quite sufficient and I suspect even one number fewer still will work ok. As for making ...

thank you, here is what i have. X(1.53768425g)+Y(1.844680696g)=0.944g X(1.574765922g)+Y(1.902934537g)=0.953g to solve this i know i need to use a system of equations, but i'm having trouble setting the coefficients to equal each other.

thank you so much for your help. this is what i have thus far: X(331.74g/2*107.87g) + Y(253.33g/137.33g)=0.944g which is: X(1.54g)+Y(1.84g)= 0.944 is that correct? how would i solve for the nitrates? we didn't measure each one separately--we measured the original sample. t...

My chem class just finished a lab in which the objective was to find the percentage of silver and barium in a nitrate salt mixture by precipitating the chromates, separating out the precipitate from the solvent and spectator ions via filtration, and analysis of the combined pr...
