Answer

Answer:

1.10×10⁻² g NaOH

Explanation:

Step1: Find molar mass of NaOH

The molar mass of Na (sodium) is approximately 22.99 g/mol, O (oxygen) is approximately 16.00 g/mol, and H (hydrogen) is approximately 1.01 g/mol. So the molar mass of NaOH, $M = 22.99+16.00 + 1.01=40.00$ g/mol.

Step2: Use mass - mole relationship

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