concentration of a stock solution with 1.98 g and 50ml

Concentration (in g/mL) = mass (in g) / volume (in mL) Given: Mass of solute (1.98 g) Volume of solution (50 mL) Concentration = 1.98 g / 50 mL Now, let's calculate the concentration: Concentration = 1.98 g / 50 mL Concentration = 0.0396 g/mL So, the concentration of the stock solution is 0.0396 g/mL
