Question

A team of scientists claim that they have discovered a new experimental
method for determining percent composition. Which of the following is
necessary for the claim to be considered valid?
A. The method must support the law of conservation of mass.
B. The percent compositions for any two compounds made from the
same elements must be the same.
C. Each atom must contribute the same mass to the compound.
D. All scientists using the new method must get the same results.

Answer 1

Answer:

Option C

Explanation:

The new method must support the law of definite proportions which means that if one mole of compound is distributed percentage wise then the sum of % share of each element must be equal to one mole of compound and this percentage distribution always remains the same in all conditions

Hence, option C is correct
