Answer:
[tex] \fbox{0.3125 M}[/tex]
Given:
- Given mass of NaOH = 30 gram
- Molar mass of NaOH = 40 gram
- Volume = 2.40 litres
To find:
Molarity = ?
Solution:
Molarity is nothing but the number of moles of solute dissolved in per litre of solution. given by formula,
[tex]Molarity = \frac{given \: mass}{molar \: mass \times Volume}[/tex]
[tex] \sf Molarity \: = \frac{30}{40 \times 2.4} = 0.3125 \: M[/tex]
