Question

If you dissolve 8 grams NaOH in 0.1L of water what is the molarity of NaOH is solution? how many miles per liter do you have

Answer 1

2 mol/L

Step-by-step explanation:

molarity = moles/litres

NaOH = 23 + 16 + 1 = 40 g/mol

`? \: mol \: naoh \: = 8 \: g \: naoh \: * \\ (1 \: mol \: naoh)/(40 \: g \: naoh) = 0.2 \: mol \: naoh`

molarity = 0.2 mol/0.1 L = 2 mol/L
