Answer :
Explanation :
Technically or logically it is possible only once. As if you subtract 5 from 25 at first te result will be 20. Now, you can't subtract 5 from 25 since the left number is 20. But if you go mathematically, it can be done infinite times and only 5 times without going into the negatives.

Answer : 1. "63 g/mol"
Explanation :
Answer: A) 63 g/mol Explanation: Calculation of molar mass of HNO3: Atomic masses of H, N, O are 1, 14, 16 respectively Now the molar mass of HNO3 is HNO3 = 1X1 + 1X14 + 3X16 = 1 + 14 + 48 = 63 g/mol or amu.

Answer : 4. "50 kmph"
Explanation :
Answer: D) 50 kmph Explanation: Speed of the train relative to man = (125/10) m/sec = (25/2) m/sec. [(25/2) x (18/5)] km/hr = 45 km/hr. Let the speed of the train be 'S' km/hr. Then, relative speed = (S - 5) km/hr. S - 5 = 45 => S = 50 km/hr.

Answer : 3. "P1V1 = P2V2"
Explanation :
Answer: C) P1V1 = P2V2 Explanation: Ideal Gas Law :: The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas: P1V1T1 = P2V2T2 Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.
