So, hello students, we have a question here.
00:05
So we have a question that is given that there is a gold ring, right? and what is the mass with the gold ring? so it is given that it's gold ring, gold ring, gold ring.
00:19
So it is given that the mass of gold ring is 18 .9 ground, right? so it's 18 .9.
00:29
Now, we have given volume also.
00:32
Its volume is that means how much space it is occupying this particular ring has a volume of 1 .12 ml you can write it here 1 .12 what is the other information given in the question it is given that the density of gold is 19 .3 gram per we can write density of gold.
01:12
The next to gold is 19 .3 gram or right? so what we need to find? so we need to find the ring that is, for example, this is the ring.
01:31
This is this and this is made of pure gold or impure gold? so this is what we need to find.
01:38
Right? so first understand the concept of pure gold than impure gold.
01:42
So pure gold is self -understandable.
01:45
It means it the ring is made of only gold.
01:49
There is no other material involved in this construction...
