Sagot :

Answer: There are 0.25 moles of NaOH  in a sample that weighed 10g.

Explanation:

Given: Mass of NaOH = 10 g

Molar mass of NaOH is 40 g/mol.

Number of moles is the mass of substance divided by its molar mass.

Therefore, moles of NaOH are calculated as follows.

[tex]No. of moles = \frac{mass}{molarmass}\\= \frac{10g}{40 g/mol}\\= 0.25 mol[/tex]

Thus, we can conclude that there are 0.25 moles of NaOH  in a sample that weighed 10g.
