Question

two aqueous solutions (solution A and solution B) contain different non reactive solutes and have densities of 1.021 g/ml and 1.190 g/ml, respectively. when 40.00 ml of solution A is mixed with 10.00ml of solution B what is the density of the mixture?

im not entirely sure how to do this problem would it be

40.00ml x 1.021 =40.84
10.00ml x 1.190 =11.9
40.84+11.9 = 52.74
52.74g / 50.00 ml = 1.0548 g/ ml

Answer 1

That looks ok to me but I would clean it up a bit.
40.00ml x 1.021 =40.84g A
10.00ml x 1.190 =11.9g B
40.84+11.9 = 52.74 = total grams.
52.74g / 50.00 ml = 1.0548 g/ ml

I didn't check the arithmetic.

thank you very much
