What is the mass percent of ethylene glycol in a 2.45 m solution of the ethylene glycol in water, the density of the solution is 1.07?

The mass percent of ethylene glycol in solution is 14.2 %

Explanation:

We are given:

Molarity of ethylene glycol solution = 2.45 M

This means that 2.45 moles of ethylene glycol is present in 1 L or 1000 mL of solution.

Density of solution = 1.07 g/mL

Volume of solution = 1000 mL

Putting values in above equation, we get:

Moles of ethylene glycol = 2.45 moles

Molar mass of ethylene glycol = 62 g/mol

Putting values in above equation, we get:

Mass of solution = 1070 g

Mass of ethylene glycol = 151.9 g

Putting values in above equation, we get:

Hence, the mass percent of ethylene glycol in solution is 14.2 %

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
