... 0.05M because of the ratio 2:1. In the formula of succinic acid below n is a whole number between 1 and 4. So therefore first I need to calculate the relative molecular mass of succinic acid. HOOC(CH2)nCOOH H = 1 O = 16 C = 12 Mr when n = 1 1+16+16+12 (12+2) 12+16+16+1 = 104 Mr when n = 2 1+16+16+12 [(12+2) x2] 12+16+16+1 = 118 Mr when n = 3 1+16+16+12 [(12+2) x3] 12+16+16+1 = 132 Mr when n = 4 1+16+16+12 [(12+2) x4] 12+16+16+1 = 146 From these calculations I can see that I need between 104g and 146g in 1 litre to equal 1M. But I want the solution in 250cm3, so therefore I need to divide the weights by 4: n = 1 104 = 26g So I need between 26g and 36.5g in 250cm3 to make a 1M 4 solution. n = 4 146 = 36.5g 4 I also want ...
