Answer:
0.03g
Explanation:
Given parameters:
Number of moles of Na = 0.00125mole
Unknown:
Mass in grams of Na = ?
Solution:
To find the mass of this substance, we simply multiply the number of moles with the given molar mass of Na.
Mass of Na = number of moles x molar mass
Mass of Na = 0.00125 x 23 = 0.03g
<u>Answer:</u> The molality of magnesium chloride is 4.93 m
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute 
= 56.3 g
= Molar mass of solute = 95.2 g/mol
= Mass of solvent = 0.12 kg
Putting values in above equation, we get:
Hence, the molality of magnesium chloride is 4.93 m
