AP EAMCET · Chemistry · Some Basic Concepts of Chemistry
An alloy of metals X and Y weighs contains atoms X and in the ratio of . The percentage of Metal X in the alloy is by mass. If the atomic mass of X is , what is the atomic mass of metal Y.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
According to mole concept Mass of metal X in alloy = 12×20100 Mass of metal Y in alloy = 12-2.4 =9.6 g Moles of X = 2.440 Now, Number of atoms of X = 2.440×6.023×1023 = 3.61×1022 Number of atoms of…
