Answer to Question #156919 in General Chemistry for Teera

Question

Consider two solids, one (A) with a density of 2.79 g/mL, and the other (B) with a density of 7.91 g/mL.

a) If you mix 1.00 mL of each of the two substances together, what is the density of the mixture?...................g/ml

b) If you mix 1.00 g of each of the two substances together, what is the density of the mixture?...................g/ml

Answer 1

$a). \frac{2.79+7.91}{1+1} =5.35$

$b). \cfrac{1+1}{\cfrac{1}{2.79}+\cfrac{1}{7.91}}$ =4.125
