Question

tekanan uap jenuh air murni pada suhu 20°C adalah 18 mmHg.apabila pada temperatur yang sama sebanyak 120 gram zat x dilarutkan dalam 990 gram air,tekanan uap larutan menjadi 17,37 mmHg,hitunglah massa molekul relatif zat x ?

Answer 1

I know this isn't the answer but here's an English translation
The saturated vapor pressure of pure water at 20 ° C is 18 mmHg. If at the same temperature as much as 120 grams of x-substance dissolved in 990 grams of water, the vapor pressure of the solution becomes 17.37 mmHg, calculate the relative molecular mass of the substance x?
