Hello students, let's solve this question here.
00:03
First we need to find out the volume of the single water particle i .e.
00:08
Volume of the particle is equal to 4 by 3 into pi into r cube.
00:15
Then substitute the values i .e.
00:17
4 by 3 pi into the r value is 5 into 10 raise to minus 6 the whole cube.
00:26
Hence next we need to calculate the total number of particles in 1 dm cube of water i .e.
00:40
Volume of water is equal to 1 dm cube it is equal to 0 .001 meter cube.
00:50
Now we can find out the total number of particles by dividing the volume of water by the volume of a single particle i .e.
00:59
The number of particles is equal to the volume of water divided by the volume of particle.
01:13
So here we will get the volume of particle value as 5 .233 into 10 raise to minus 16.
01:22
Let's substitute on to this equation hence the number of particle will be the volume of water is 0 .001 divided by 5 .233 into 10 raise to minus 16...
