Calculate the molality of 75.0 grams of MgCl2 (molar mass=95.21 g/mol) dissolved in 500.0 g of solvent.

The molality of magnesium chloride is 1.58 m

Explanation:

To calculate the molality of solution, we use the equation:

Where,

= Given mass of solute (magnesium chloride) = 75.0

= Molar mass of solute (magnesium chloride) = 95.21 g/mol  

= Mass of solvent = 500.0 g

Putting values in above equation, we get:

Hence, the molality of magnesium chloride is 1.58 m

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
