NEET Chemistry Percentage Composition MCQ Question
Imagine a diagram showing a compound with its constituent elements labeled as A, B, and C. If A, B, and C represent different elements in a compound with a fixed and definite ratio by mass, how would you determine the percentage composition of element C in the compound?
Calculate the mass of C and divide by the total mass of the compound, then multiply by 100.
Count the number of atoms of C and divide by the total number of atoms in the compound, then multiply by 100.
Calculate the volume of C and divide by the total volume of the compound, then multiply by 100.
Measure the density of C and divide by the total density of the compound, then multiply by 100.
Correct Answer
Detailed Explanation
Percentage composition is determined by dividing the mass of each element by the total mass of the compound and multiplying by 100, reflecting the fixed ratio of elements.
