Hello students, hope you are doing great.

In this question, we have to calculate the molar mass of the given molecules.
00:08
So the first molecule that we are given here is calcium carbonate.
00:12
To find out the muly mass of calcium carbonate, we have one calcium here and the mass of one calcium atom is equals to 1 into 40.
00:20
That is equals to 40.
00:22
For one carbon, it is 1 into 12, that is equals to 12.
00:26
And here we have 3 oxygen.
00:28
Therefore, 3 into 16, that is.
00:31
Is equals to 48 and the sum of this is 100 gram per mole therefore the molar mass of calcium carbonate is 100 gram per mole second mineral given here is halite whose molecular formula of is n acl so here we have sodium that is equals to 1 into 23 is equals to 23 1 chlorine chloride ion therefore 1 into 35 .5 is equals to 35 .5 is equal to 35.
01:04
5 .5 and total it is 58 .5 gram per mole.
01:11
Therefore molar mass of nacl is a 58 .5 gram per mole.
01:19
Next mineral we are given here is beryl and its molecular formula is b .e3, al2, si6o18.
01:32
So here we have 3 beryllium.
01:34
That is equals to 3 into 9.
01:38
That is the mass of beryllium equals to 27 2 into al so 2 into 27 is equals to 54 6 silicon atoms so 6 into 28 is equals to 168 we have 18 oxygen here therefore 18 into 16 is equals to 288 so total it is 537 gram per mole and the mass of beryl is 537 gram per mole next mineral we have here is malachite and its molecular formula is co2 oh h2 co3 so here we have two copper atoms so 2 into 63 .5 is equal to 127 here we have 2 oh h therefore 2 into 7 17 is equals to 34...
