What is the molality of a solution when 0.50 moles glucose is dissolved in 750 g of water?
xxMikexx [17]

Answer:

0.67mol/Kg

Explanation:

The following were obtained from the question:

Mole of solute = 0.50mol

Mass of solvent = 750g = 750/1000 = 0.75Kg

Molality =?

Molality = mole of solute /mass of solvent

Molality = 0.5/0.75

Molality = 0.67mol/Kg

Please leave workings as well
yulyashka [42]

Answer:

15g

Explanation:

The equation for the reaction is given below:

CaO + SO2 —> CaSO3

Molar Mass of CaO = 40 + 16 = 56g/mol

Molar Mass of CaSO3 = 40 + 32 + (16x3) = 40 + 32 + 48 = 120g/mol

From the equation,

56g of CaO produced 120g of CaSO3.

Therefore, 7g of CaO will produce = (7 x 120)/56 = 15g of CaSO3

Therefore, 15g of CaSO3 is produce
