Question

State the general form of Raoult's law and give a mathematical expression for the same. A solution containing 15 g of non-volatile solute dissolved in 45 g of water has a vapour pressure of 1400 Pa at 298 K. Further, 9 g of water is then added to the solution and the new vapour pressure becomes 1450 Pa. Calculate the molar mass of the solute.​

Answer 1

Answer:

idkkkk

I am sorryyy

Explanation:

thanks

Answer 2

Answer:

By definition, if a mass m is under SHM its acceleration is directly proportional to displacement. and, since T = 1f where T is the time period, These equations demonstrate that the simple harmonic motion is isochronous (the period and frequency are independent of the amplitude and the initial phase of the motion).
