Answer:
Molarity for the solution is 1.48 M
Explanation:
Molarity involves the moles of solute that are contained in 1L of solution. It is a sort of concentration. The most usual.
7.73 by mass involves the mass of solute that are contained in 100 g of solution, so this one of ethylene glycol contains 7.73 g of it.
Let's determine the moles of solute
7.73 g / molar mass of ethylene glycol = moles
7.73 g / 62 g/mol = 0.124 mol
If the mass of solution is 100 g, we can determine the volume with density.
Density = Mass / Volume
Volume = Mass / Density
Volume = 100 g / 1.19 g/mL = 84.03 mL
In conclusion, 0.124 moles are contained in 84.03 mL
Molarity is mol/L, so let's convert the volume in L
84.03 mL . 1L / 1000 mL = 0.08403 L
0.124 mol / 0.08403 L = 1.48 M
