In the question, the details of weighing magnesium ribbon is given.
00:05
So this is the table given in the question and we just have to fill the rows of these table.
00:11
So here, the first one is row 4 to find the mass of magnesium and it is given that the value can be found out by the line 2, this 1 minus the line 1.
00:25
That will be giving the magnesium ribbon mass.
00:31
So that will be this value minus this value which is equal to 0 .22.
00:42
Here it will be this value minus this value and here it is 0 .57.
00:51
Now the third row the magnesium is heating means it is reacting with the o2 molecule.
00:56
Fuel and here mg o will be formed after this heating and a mass of mgo is to be found out which is found out by the line 3 minus line 1.
01:07
So that will be this value minus this value which is equal to 0 .37 and here it will be this value minus this value which is equal to 0906.
01:24
The next row is mass of o combined.
01:28
So that can be found out by the line 5 minus line 4, that is this line minus this line, which will give the extra o that you got combined.
01:39
So we have this value minus this value which is equal to 0 .15 and here this value minus this value which is equal to 0 .35...
