The question says to arrange all the densities, arrange densities from smaller to larger, or we can say in the ascending order.
00:18
And what is given here? the densities of the elements are given here.
00:23
For silver, it is 87 .6 lb divided by gal.
00:30
The density for iron is given, which is 7 .87 multiply by 10 power 3.
00:36
Kg per meter cube.
00:40
The density for lead is given which is 6 .55 o's per meter per meter cube and the density of copper which is given as 8 .96 gram per centimeter cube.
00:56
So we will see the explanation for it.
01:01
First of all we will try to bring all the densities to its standard.
01:06
And what is standard standard way to calculate density is gram per centimeter cube and we can find for copper this is gram per centimeter cube means the density of copper is already in its standard form so now we have to find the density first of all we will see for silver you will talk about silver first of all so if we talk that one pound or we can say lb is equal to 0 .45 kg or i can write 450 gram.
01:49
This is the value for one pound.
01:51
And what is the value for one gal? one gal or one galon we can say.
01:56
It is gal.
01:57
What is the value of it? it is 3 .765 liters, which i can also write 3 .765 multiplied by 10 power 3 cm cube.
02:11
I can also write this.
02:14
So if we calculate the density here, the density of silver which is represented by ag, this will be 450 divided by 3 .7 multiplied by 10 power 3.
02:32
And what is the density given here? that is 87 .6...
