Best ResponseYou've already chosen the best response.1Molarity=moles/volume(in lts.) for h2so4 : 1M=n(moles)/0.1 n=0.1 total weight of final solution = 100 x 1.5 +400 = 550gm volume of final solution = 550/1.25 = 440ml = 0.440L molarity of h2so4 in final solution = 0.1/0.440 = 0.227M

Best ResponseYou've already chosen the best response.1it is given that the final density is 1.25g/ml the final mix has h2so4 and h2o total mass of final mixture as calculated above is = 550gm total volume of final mix. = vol. of h2so4 + vol. of h2o = 100+400 = 500 so final density of final solution = mass/volume = 550/500 = 1.1gm/ml but in the question the final density given is 1.25gm/ml now how is that possible??

Best ResponseYou've already chosen the best response.0when you dilute a solution, does the density increase or decrease?

Best ResponseYou've already chosen the best response.0can you use the density formula?

Best ResponseYou've already chosen the best response.1the way i showed that the final density is 1.1 is also correct.

Best ResponseYou've already chosen the best response.1@hwyl how will you prove that density is not 1.1 and its 1.25??

Best ResponseYou've already chosen the best response.0You are meant to calculate the concentration of H2SO4 and then to use that to find the final density of the solution and CHECK that it is 1.25.

Best ResponseYou've already chosen the best response.1@ShizukaTheOtaku no we don't have to check whether the density given is correct or not rather we are given the density to find the molarity. But i wished to check whether the density given was correct or not and in the calculation above which i posted the density is comming out to be different from what is given in the question.
