1. The problem statement, all variables and given/known data 2. Relevant equations M = n/L 3. The attempt at a solution My answer is A) 1.02 M but im not sure if i did this right. Can someone explain why this might be right or wrong? I got moles of Al(NO3)3 =0.0393 moles I got moles of Ca(NO3)2 = 0.0426 moles by multiplying liters and molarity then i added the moles of NO3 in each of them . So for Al(NO3)3 , the mole ration is 1/3 so i get that there is 0.1179 moles NO3 from that compound. then i added the NO3 from Ca(NO3)2 using the same ratio so i get 0.0852. I added these moles of NO3 together and divided by total liters of solution and got 1.02 M My question is am i suppose to treat each compound as it were to break into nitrates and use the mole ratios on each of them to find the amt of nitrates they break down into? I wasn't sure! At first, i thought i had to find a limiting reactant and use only one compound to calculate nitrate.
