The highest number of helium atoms is in

  1. A
    4 g of helium
  2. B
    2.271098 L of helium at STP
  3. C
    4 mol of helium
  4. D
    4 u of helium
View Answer & Solution

Correct answer · Option C

4 mol of helium

Explanation

4 mol of helium contains \( 4 N_A \) atoms, which is the highest compared to 4 g (\( 1 N_A \) atoms), 2.27 L at STP (\( 0.1 N_A \) atoms), and 4 u (1 atom).

Given below are two statements: Statement I : The boiling point of three isomeric pentanes follows the order n-pentane > isopentane > neopentane Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point. In the light of the above statements, choose the most appropriate answer from the options given below:→Match List I with List II. List I (Conversion) A. 1 mol of \( H_2O \) to \( O_2 \) B. 1 mol of \( MnO_4^- \) to \( Mn^{2+} \) C. 1.5 mol of Ca from molten \( CaCl_2 \) D. 1 mol of FeO to \( Fe_2O_3 \) List II (Number of Faraday required) I. 3F II. 2F III. 1F IV. 5F Choose the correct answer from the options given below:→Among Group 16 elements, which one does NOT show -2 oxidation state?→Match List I with List II.
