TS EAMCET · Chemistry · Some Basic Concepts of Chemistry
Which one of the following has the same number of atoms as are in \(6 \mathrm{~g}\) of \(\mathrm{H}_2 \mathrm{O}\) ?
- A \(0.4 \mathrm{~g} \mathrm{He}\)
- B \(22 \mathrm{~g} \mathrm{CO}_2\)
- C \(1 \mathrm{~g} \mathrm{H}_2\)
- D \(12 \mathrm{~g} \mathrm{CO}\)
Answer & Solution
Correct Answer
(C) \(1 \mathrm{~g} \mathrm{H}_2\)
Step-by-step Solution
Detailed explanation
n \(\left(\mathrm{H}_2 \mathrm{O}\right)=\frac{6 \mathrm{~g}}{18.0 \mathrm{~g}}=\frac{1}{3}\) or number of \(\mathrm{H}_2 \mathrm{O}\) molecules \(=\frac{1}{3} \mathrm{~N}_{\mathrm{A}}\). \(\Rightarrow\) Total number of atoms in…
