Hello students, in this question we have to answer some questions about the hydrate formula of copper.
00:06
Now copper sulfate exists in the form of a pentahydrate.
00:11
Now let's answer different questions.
00:15
In the first question we have to tell the mass of copper sulfate pentahydrate.
00:21
So let's calculate it.
00:23
Copper has a mass of 63 .5 atomic mass unit.
00:28
Then we have one sulfur atom which will have a mass of 32.
00:31
Then we have four oxygen atoms.
00:34
Each oxygen atom is equal to 16 amu.
00:37
Now we have five water molecule.
00:41
Mass of one molecule of water will be 2 for hydrogen and 16 for oxygen.
00:48
So after calculation now in the next question we have to tell the mass of anhydrous copper sulfate.
01:03
So in this mass we will not have to consider the mass of water.
01:08
Therefore mass of copper sulfate only will be equal to 159 .5.
01:15
Now in the next question we have to tell the mass of water that has been involved in the hydration...
