Hey there :
Molar mass of NaCl = 58.44 g/mol
Number of moles :
n = mass of solute / molar mass
n = 58 / 58.44
n = 0.9924 moles of NaCl
Volume = 1.0 L
Therefore:
Molarity = number of moles / volume ( L )
Molarity = 0.9924 / 1.0
Molarity = 0.9924 M
Hope that helps!
Answer:
Mole fraction of
= 0.58
Mole fraction of
= 0.42
Explanation:
Let the mass of
and
= x g
Molar mass of
= 33.035 g/mol
The formula for the calculation of moles is shown below:
Thus,
Molar mass of
= 46.07 g/mol
Thus,
So, according to definition of mole fraction:

Mole fraction of
= 1 - 0.58 = 0.42
