The vapour pressure of water at $23^{\circ} C$ is $19.8 \ mm$. $0.1 \ mole$ of glucose is dissolved in $178.2 \ g$ of water. What is the vapour pressure (in $mm$) of the resultant solution?

Doctors use a stethoscope to hear the sounds produced during each cardiac cycle. The second heart sound is heard when:

The arithmetic mean of a set of observations is $\bar{X}$. If each observation is divided by $\alpha$ and then increased by $10$,then the mean of the new series is:

$3.2$ moles of hydrogen iodide were heated in a sealed bulb at $444 \, ^oC$ until the equilibrium state was reached. Its degree of dissociation at this temperature was found to be $22 \%$. The number of moles of hydrogen iodide present at equilibrium are:

If $\int e^x(1+x) \cdot \sec ^2(x e^x) \, dx = f(x) + \text{constant}$,then $f(x)$ is equal to

$A$ scion is grafted to a stock. The quality of fruits produced will be determined by the genotype of
