Answer

Explanation:

Step1: Find molar - mass of NaOH

The molar - mass of Na ($M_{Na}=22.99\ g/mol$), O ($M_{O}=16.00\ g/mol$), and H ($M_{H}=1.01\ g/mol$). The molar - mass of NaOH, $M = M_{Na}+M_{O}+M_{H}=22.99 + 16.00+1.01=40.00\ g/mol$.

Step2: Calculate mass of NaOH

Use the formula $m = n\times M$, where $n = 2.75\times10^{-4}\ mol$ and $M = 40.00\ g/mol$. Then $m=(2.75\times10^{-4}\ mol)\times(40.00\ g/mol)=1.10\times10^{-2}\ g$.

Answer:

$1.10\times 10^{-2}\ g\ NaOH$
