Question

Consider the following data: Element Atomic weight A 12 B 35.5 A and B combine to form a new substance X. If four moles of B combine with one mole of A to give one mole of X, then the weight of one mole of X is (A) 47.5 g (B) 83 g (C) 154 g (D) 166 g

Tardigrade Admin · Accepted Answer

A+4 B → X ( i.e., .A B4) Hence, 1 mol of X=12+4 × 35.5=154 g

Q. Consider the following data :

Element Atomic weight

A 12

B 35.5

$A$ and $B$ combine to form a new substance $X$ . If four moles of $B$ combine with one mole of $A$ to give one mole of $X$ , then the weight of one mole of $X$ is

$47.5 g$

$83 g$

$154 g$

$166 g$

$A + 4 B \to X$ ( i.e., $A B_{4})$

Hence, $1 m o l$ of $X = 12 + 4 \times 35.5 = 154 g$
