Hello everyone let's have a look at the question.
00:02
So here we have to see the number of moles of sio2, moles reacted will be equal to 15 divided by 60 .09.
00:20
So total will be equal to 0 .25 moles.
00:25
So here we have to calculate the for 0 .25 moles of sio2, how much will be the mass of s .i .f .4.
00:36
So for that, 0 .25 moles of s .i .o .2.
00:45
So, reacts with 0 .5 moles of 0 .25 moles of sif4.
00:56
So here, that will be equal to 0 .25 multiplied by the molar mass, molar mass of s .i .f .4.
01:13
So that will be equal to 0 .25 which is multiplied by 104 .0 .0 .0.
01:19
So that will be equal to 26 .02 grams of sif4.
01:26
This is the answer to our first part.
01:29
So now coming to the second part, that is, here, moles of sio2 reacted will be equal to sif4...
