Astudent reported the following composition of an unknown mixture, 25% nh4cl, 30% nacl, and 50% sio2. assuming the student's calculations are correct, explain the error.

The composition of the unknown mixture is more than 100 %, which is not possible.

Explanation:

Composition of a mixture is defined as the sum of the amount of substances that are present in the mixture. The maximum composition of a mixture can be 100 %

We are given:

Composition of ammonium chloride in the mixture = 25 %

Composition of sodium chloride in the mixture = 30 %

Composition of silicon oxide in the mixture = 50 %

Composition of mixture = (25 + 30 + 50) = 105 %

As, the measured value of unknown mixture is more than the true value which is 100 %. Thus, the error lies here only.

Hence, the composition of the unknown mixture is more than 100 %, which is not possible.

i have no clue hope you find the answer
