Answer of this question is here, alloy is alcocrfeni 2 .1.
00:18
Okay, so atomic weight and density for them is atomic weight and density.
00:28
For aluminium 26 .98 and density is 2 .7 gm per cc.
00:41
Okay, now for co equals to 56 .93 and 8 .90 per cc.
00:52
For cr this will be equals to 51 .99.
00:56
For fe equals to 55 .84 and for ni equals to 58 .69.
01:07
And this will be equals to 7 .19, 7 .86 and 8 .98.
01:23
Okay, so the molecular weight of alloy is adding all the weights 26 .98 plus 56 .93 plus 57 .99 plus 55 .84.
01:50
Plus 2 .1 into 58 .69.
01:57
So, after adding this will be equals to 316 .989 gm.
02:03
Okay, now the density of an alloy, density of alloy equals to, it is mass 100 gm is divided by its volume.
02:26
Divided by its volume.
02:31
Okay, so for aluminium in 100 gm, alloy equals to 26 .93 divided by 316 .985 into 100.
02:53
So, this will be equals to 989.
02:57
This will be equals to after calculation 8 .52.
03:04
And for co equals to 58 .93 divided by 316 .989 into 100.
03:15
So, this will be equals to 18 .59.
03:19
For cr this will be equals to 51 .99 divided by 316 .989 into 100.
03:30
So, this will be equals to 16 .40 gm.
03:33
And for fp this will be equals to 55 .84 divided by 316 .989 into 100.
03:44
So, this will be equals to 17 .600.
03:48
And for ni will be equals to 2 .1 into 58 .69 divided by 316 .989 into 100...
