A mixture of 1 mole of and 1 mole of is taken. Which of the following is/are correct? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$M_{avg} = \frac{n_1M_1 + n_2M_2}{n_1 + n_2} = \frac{1(2) + 1(4)}{2} = 3$ g/mol. <br>$\chi_{H_2} = 1/2 = 0.5$. <br>$\text{Mass} = 2 + 4 = 6$ g. <br>$\text{Atoms} = (1 \text{ mol } H_2 \times 2) + (1 \text{ mol } He \times 1) = 3 N_A$.
