Part II. The molality of a solution is the number of moles of the solute that is dissolved in 1000 g of solvent. Using the values for the mass of sodium chloride, its molar mass (58.443 g/mol), and the mass of water solvent that you used, calculate and enter the molality of the sodium chloride solution to three significant digits, e. g. 0.484.

Explanation:

The molality of a solution, m is defined as the number of moles of the solute that is dissolved in 1 kg of solvent.

m = number of moles/kilogram of solvent

Attached is the answer and complete question.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
