\(200\, g\, mol^{-1}\)
For isotonic solution \(\pi_{1}=\pi_{2}\)
or, \(C _{1}= C _{2}\) (conc. in mol/lit.)
(Urea solution) (unknown solution)
\(\frac{10}{60}=\frac{5 \times 1000}{ m _{ w } \times 100}\)
\(m _{ w }=300 \,gm\, mol ^{-1}\)
So, the correct option is (B): \(300 \,g \,mol^{-1}\)
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
The solutions can be classified into three types:
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
