Explanation:

Dipole moment is defined as the measurement of the separation of two opposite electrical charges.

$H_{2}O$ is a bent shaped molecule with a dipole moment of 1.87.

$H_{2}S$ is also a bent shaped molecule with a dipole moment of 1.10.

$H_{2}Te$ is a also a bent shaped molecule and has a negligible dipole moment.

$H_{2}Se$ has a dipole moment of 0.29.

Therefore, given molecules are arranged according to their increasing dipole moment as follows.

$H_{2}Te$ < $H_{2}Se$ < $H_{2}S$ < $H_{2}O$

The mean is 65.72 , median is 81 and mode is 52

Step-by-step explanation:

Stem Leaf

5 2, 2, 2.

8. 1,5,9

9. 3,4,6

1. 2,7

Number : 52,52,52,81,85,89,93,94,96,12,17

Arrange in ascending order :

12,17,52,52,52,81,85,89,93,94,96

$Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Mean =\frac{12+17+52+52+52+81+85+89+93+94+96}{11}$

Mean =65.72

$Median = \frac{n+1}{2} \text{th term}=\frac{11+1}{2}=6 \text{th term} = 81$

Mode = most occurring number = 52

Hence The mean is 65.72 , median is 81 and mode is 52
