The final volume of the solution is 284 mL. What is the concentration of CuSO4 in the final solution, in mol/L?

mass = 1.787 g
1.787 g of CuSO4•5H2O = 7.157 × 10^-3 mol

0.0252mol/L

Explanation:

The following data were obtained obtained from the question:

Volume of solution = 284mL = 284/1000 = 0.284L

Mole of CuSO4 = 7.157 × 10^-3 mol

Molarity =?

Molarity = mole/Volume

Molarity = 7.157x10^-3 /0.284

Molarity = 0.0252mol/L

The concentration of the solution is 0.0252mol/L

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
