Manipal MET2012ChemistrySome Basic Concepts of Chemistry
A compound has the molecular formula X₄ O ₆ . If 10 g of X₄ O ₆ has 5.72 ~g X , then calculate atomic mass of X .
Options
- A32 amu
- B67 amu
- C64 amu
- D98 amu
Correct answer
A. 32 amu
Step-by-step solution
Molecular weight of X₄ O ₆=(4 a+96) array r (4 a+96) g ₄ O ₆ contains X=4 a ~g 10 ~g X ₄ O ₆ contains X= 4 a 10 4 a+96 5.72= 4 a 10 4 a+96 array aligned 22.88 a+549.12 & =40 a 17.12 a & =549.12 a & =32.07 amu . aligned
