Even in the question is mass of sodium bicarbonate.
00:09
Sodium bicarbonate value is nh co3, 25 .5 grams.
00:26
Nah co3 decomposes to produce sodium carbonate, n .a2, co3, water, sodium carbonate, water and carbon dioxide.
00:43
So let us represent that in the form of equation.
00:46
2nah co3 gives rise to na2 co3 plus co2 plus co2 plus water that is h2o.
01:02
Molar mass of nah co3 equal to 23 plus 1 plus 12 plus 16 multiplied with 3 uses 84 grams per mole.
01:31
So let us make the formula.
01:34
Number of moles of nah co3 equal to mass divided by molar mass.
01:52
This is equal to 25 .5 grams divided by 84 grams per mole.
02:02
On simplification we are going to get 0 .3036 moles.
02:11
Number of moles of nah co3 is equals to 0 .3036 moles.
02:28
According to stichometry we found that two moles of nah co3 decompos to produce one more of carbon dioxide therefore one mole of nahs half moles of co2 therefore 0 .3036 moles of nhh co3 will produce 0 .3036 multiplied with 1 divided by 2 half moles of co2.
03:27
This is equal to 0 .1518 moles of carbon...
