Answer:
1.7 M
Explanation:
Concentration is the number of moles of solute dissolved in 1 L of solution
Concentration = number of moles of solute / volume of solution
Number of moles of solute needs to be calculated first
Mass of methanol - 12.5 g
Molar mass of methanol - 32 g/mol
Number of methanol moles - 12.5 g / 32 g/mol = 0.39 mol
Therefore concentration is = 0.39 mol / 0.230 L = 1.7 mol/L
Concentration is 1.7 M
