\(3.011 \times 10^{22}\) atoms of an element weight \(1.15 \mathrm{~g}\). The atomic mass of the element is
- A 10 amu
- B 2.3 amu
- C 35.5 amu
- D 23 amu
Answer & Solution
Correct Answer
(D) 23 amu
Step-by-step Solution
Detailed explanation
Given, \(3.011 \times 10^{22}\) atoms of an element weight = 1.15 g Now, \(6.023 \times 10^{23}\left(N_A\right)\) atoms of an element will weight \[ =1.15 \times \frac{6.023 \times 10^{23}}{3.011 \times 10^{22}}=23 \mathrm{~g} \] The atomic mass of the element is…
