NEET MOCK TEST 6

NEET Mock Test 6 is a practice test built along the lines of the NEET pattern, with questions drawn from Physics, Chemistry and Biology. Attempting it in one sitting gives you a sense of how you manage time across sections and where accuracy drops. Review the answers afterwards to see which topics need more work.

A solution of two volatile liquids A and B has a total vapor pressure of 280 mm Hg. If the vapor pressure of pure A is 4

Given: A solution of two volatile liquids A and B has a total vapor pressure of 280 mm Hg. If the vapor pressure of pure A is 400 mm Hg and that of pure B is 160 mm Hg, what is the mole fraction of B in the solution? These values define the system as per NCERT data.
