Sodium hydroxide (NaOH) is a strong base that is very corrosive. What is the mass of 2.75 × 10-4 moles of NaOH?

3.24 x 10–3 g NaOH

1.10 x 10–2 g NaOH

6.10 x 10–2 g NaOH

6.50 x 10–2 g NaOH

The mass of  2.75 ×   [tex]10^{-4}[/tex]moles NaOH will be 1.1 x  [tex]10^{-2}[/tex] grams

Mass/mole relationship

Recall that:

Mole = mass/molar mass.

Thus, mass = mole x molar mass.

In this case, the mole is  2.75 × [tex]10^{-4}[/tex] moles and the molar mass of NaOH is 40 g/mol.

Mass =  2.75 ×  [tex]10^{-4}[/tex]x 40 = 1.1 x  [tex]10^{-2}[/tex] grams
