The fraction of the no of moles of sio2 and the no of moles of al2o3 required to form 1 mole of kalsilite(kalsio4)is

sir.in the beginning of the Q.(the fraction of the moles required)the fraction of moles is asked.does it directly mean to find mole fraction?

for which in the last step u did 0.5/total moles for al2O3

I followed according to question. if it is said how many moles of Al2O3 or Sio2 is used for 1 mole of kalsillite then it would be directly 0.5 and 1 mole respectively but fraction of mole is asked so i find out the fraction from total 2 mole which is 0.5 of al203 + 1 mole of SiO2 and .5 mole of k2o .

sir what you are saying i understood. but why there is so much variation between your answers and rahul pandey sir answers

this is creating confusion in my mind.which one i should follow

Rahul Pandey is a mentor here i am not able to see his answers as i am not a friend of him. May be i am wrong i but i followed the steps that's why i always ask for validation.. Don't panic i will validate with a chemistry friend and inform you quickly.

ok sir.please validate.

anu A balanced reaction have equal mole on both side no matter the individual moles of reactant species. means 1 mole of Al2O3 is formed so 1mole of reactant species also to be consumed. so directly 0.5 and 1mole will be the answer here.

The last step of my answer has to be omitted and i apologise for this mistake .we also learn as well you guys are constantly polishing us . Thank you

for this question a last step was missing.

i got it today..the question is asking for a single value and it mentions the fraction of no of moles of sio2 and al2o3 it is 1/0.5=2

answer is 2

ohh Ratio was asked!!!

yes sir

Now you know the concept you can do questions related to this 😃

in the question sir fraction of the moles required, does it mean to find Mole fraction?

The question doesn't specify that thing clearly. Fraction usually means part, which is calculated in this question.
