Answer: 10.3 mol/l
Explanation: Molality = concentration c = n/V
Amount of substance n = m/M = 150 g / 58.44 g/mol =
2,5667 mol . c = 2.5667 mol / 0.25 l = 10.2669 mol/l
c =
Answer:
14. the metal is tin which it density is equal 7.3g/cm^3
Answer: 3390
Explanation:
Since this problem already gives is the equilibrium values, all we have to do is to plug them into the formula for
.
