Answer: pretty sure its 0.214 moles * 40.3g/mole = 8.6g (2 sig figs) of MgO, and
0.035 moles * 40.3g/mole = 1.4g of MgO

Explanation:
Answer : The molality of sodium chloride is, 1.79 m
Explanation :
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute (sodium chloride) = 49 g
= Molar mass of solute (sodium chloride) = 58.5 g/mol
= Mass of solvent (water) = 469 g
Now put all the given values in above equation, we get:
Hence, the molality of sodium chloride is, 1.79 m
