Question

How many moles of Naoh are in 26.7 ml of a 0.100 M NaOh solution?

Answer 1

How many moles of NaOH are in 26.7 ml of a 0.100 M NaOH solution?

Solution:

The molar concentration $(C_i)$ is defined as the amount of a constituent $(n_i)$ divided by the volume of the mixture $V$:

$$C_i = \frac{n_i}{V} = \frac{mole}{l}$$ $$1l = 1000 \, ml$$ $$V(NaOH) = 0.0267 \, l$$

Find the amount of the substance in the solution of NaOH:

$$n(NaOH) = c(NaOH) * V(NaOH)$$ $$n(NaOH) = 0.100 \, mole/l * 0.0267 \, l = 0.00267 \, mole$$

**Answer:** In 26.7 ml of a 0.100 M NaOH solution containing 0.00267 moles of NaOH
