The density of a solution prepared by dissolving 120 g of urea (mol. Mass = 60 u) in 1000 g of water is 1.15 g/mL. The molarity of this solution is:
Statement-I: For a mass M kept at the centre of a cube of side gravitational field passing through its sides is 4π GM. And
Statement-II : If the direction of a field due to a point source is radial and its dependence on the distance 'r' for the source is given as 1/r2, its flux through a closed surface depends only on the strength of the source enclosed by the surface and not on the size or shape of the surface.
In an atom, an electron is moving with a speed of 600m/s with an accuracy of 0.005%. Certainity with which the position of the electron can be located is (h=6.6×10−34kgm2s−1 " mass of electron, " e_(m) = 9.1 xx 10^(-31) kg)
The organic chloro compound, which shows complete stereochemical inversion during a SN2 reaction, is
How many different words can be formed by jumbling the letters in the word MISSISSIPPI in which no two S are adjacent?
While measuring the speed of sound by performing a resonance column experiment, a student gets the first resonance condition at a column length of 18 cm during winter. Repeating the same experiment during summer, she measure the column length to be x cm for the second resonance. Then
A value of C for which the conclusion of Mean Value Theorem holds for the function f(x)=(log)exon the interval [1, 3] is
Two liquids X and Y form an ideal solution. At 300K, vapour pressure of the solution containing 1 mol of X and 3 mol of Y is 550 mm Hg. At the same temperature, if 1 mol of Y is further added to this solution, vapour pressure of the solution increases by 10 mm Hg. Vapour pressure (in mmHg) of X and Y in their pure states will be, respectively
