Given: Molar mass of A 2 B = AB 3 <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/cc7ebad0593ed5ea3cc16bb00f468b41-.png" /> ⇒ A =2 B ∴ atomic wt. of A is 2 times of atomic wt. of B Integer answer is 2

Q. Two elements A and B which form $0.15$ moles of $A_{2} B$ and $A B_{3}$ type compounds. If both $A_{2} B$ and $A B_{3}$ weigh equally, then the atomic weight of $A$ is_______ times of atomic weight of B.

Given: Molar mass of $A_{2} B = A B_{3}$

$\Rightarrow A = 2 B$
$∴$ atomic wt. of $A$ is $2$ times of atomic wt. of $B$ Integer answer is $2$

Q. Two elements A and B which form 0.15 moles of A2​B and AB3​ type compounds. If both A2​B and AB3​ weigh equally, then the atomic weight of A is_______ times of atomic weight of B.

Given: Molar mass of A2​B=AB3​ ⇒A=2B ∴ atomic wt. of A is 2 times of atomic wt. of B Integer answer is 2

Q. Two elements A and B which form $0.15$ moles of $A_{2} B$ and $A B_{3}$ type compounds. If both $A_{2} B$ and $A B_{3}$ weigh equally, then the atomic weight of $A$ is_______ times of atomic weight of B.

Given: Molar mass of $A_{2} B = A B_{3}$

$\Rightarrow A = 2 B$
$∴$ atomic wt. of $A$ is $2$ times of atomic wt. of $B$ Integer answer is $2$
