A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows : You were asked to prepare a frequency distribution table, regarding the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city for 30 days . Using this table, find the probability of the concentration of sulphur dioxide in the interval 0.12-0.16 on any of these days.

In a first order reaction the concentration of the reactant decreases from 0.8 to 0.4 M in 15 minutes . The time taken for the concentration to change from 0.1 M to 0.025 M is :

Find the centre of the circle passing through (0,0)(3,0) and (0,5)

What volume of 0.8 M solution contains 0.1 mole of solute

In , you were asked to prepare a frequency distribution table regarding the concentration of sulphur dioxide in the air in parts per million of a certain city for 30 day . Using this table , find the probability of the concentration of sulphur dioxide in the interval 0.12 - 0.16 on any of these days .
