Question

Which of the following statements is/are correct? a. 1 mole of CH4 and 17 g of NH3 occupy same volume at NTP b. 2 moles of K weight less than that of 1 mole of Ag c. 1 atom of silver weights (108/6.022 × 1023) g d. 1 amu of CO2 is 6.023 × 1023 times heavier than 1 molecule of CO2 (A) a, b c (B) a, b d (C) b, c d (D) a, c d

a. 17 g of NH3 = 1 mole b. Atomic weight of K = 39, so 2 mole K = 74 g c. Atomic weight of Ag = 108, So 1 mol Ag = 108 g d. 44 amu of CO2 = 1 molecule 1 amu of CO2 (1/44) molecules

a. $17$ $g$ of $N H_{3} = 1$ mole
b. Atomic weight of $K = 39$ , so $2$ mole $K = 74$ $g$
c. Atomic weight of $A g = 108$ ,
So $1$ mol $A g = 108$ $g$
d. $44$ amu of $C O_{2} = 1$ molecule
$1$ amu of $C O_{2}$ $\frac{1}{44}$ molecules
