Answer:
The correct answer is 6.31 M
Explanation:
The molecular weight (MM) of NaOH is calculated as follows:
MM(NaOH) = Molar mass Na + Molar mass O + Molar mass H
= 23 g/mol + 16 g/mol + 1 g/mol
= 40 g/mol
We need the MM to convert from grams to moles. The molarity (moles of solute per liter of solution, in mol/L) can be calculated by dividing the mass into the volume in liters (195 ml = 0.195 L) and then multiplying by the MM as follows:
M = 49.24 g/0.195 L x 1 mol/40 g = 6.31 mol/L = 6.31 M
