Answer 2

$\color{red}{\huge{\underline{\underline{GIVEN\dag}}}}$

• 169g of $Na_{2}CO_{3}$

$\color{red}{\huge{\underline{\underline{SOLUTION\dag}}}}$

$Molecular\: weight(M)_{Na_{2}CO_{3}}=106$

$\color{blue}{{\boxed{Mole(n)=\frac{weight}{M_{Na_{2}CO_{3}}}}}}$

$\implies n = \frac{106}{169}$

$\color{orange}\therefore n = 0.627$

HOPE THAT HELPS!!
