Question

Observe the given figure carefully and select the correct option

• A. $W=55.8,X=16,Y=2.016,Z=58.5$
• B. $W=55.8,X=32,Y=1.008,Z=58.5$
• C. $W=55.8,X=16,Y=1.008,Z=58.5$
• D. $W=55.8,X=32,Y=2.016,Z=58.5$

Answer 1

Answer: (B)

$W=55.8,X=32,Y=1.008,Z=58.5$

$1$ mole $=$ Atomic weight of an element So, $1$ mole $=1.008g$ of $H$.

$=$ molecular weight of a compound $=58.5g$ of $NaCl(23+35.5)$

$=$ Avagadro no. of atoms $=55.8g$ of $Fe$

$=32g$ $\left(O_2\right)(16+16)$

$=18g$ $H_{2}O=(2+16)$
