if i have a molar concentration of acetic acid.046 mol/L how do i get the calculated molar mass of acetic acid
To calculate the molar mass of acetic acid (CH3COOH), you need to know its molar concentration and the volume of the solution in which it is dissolved. However, the molar concentration alone cannot directly provide the molar mass.
Here's a step-by-step process to determine the molar mass of acetic acid using its molar concentration and additional information:
1. Convert the molar concentration from mol/L to moles per liter (mol/L). In your case, the molar concentration is already given as 0.046 mol/L, so no conversion is needed.
2. Calculate the number of moles of acetic acid by multiplying the molar concentration (in mol/L) by the volume of the solution (in liters). For example, if you have 0.5 liters of the solution, the number of moles would be 0.046 mol/L x 0.5 L = 0.023 moles.
3. Determine the mass of acetic acid by multiplying the number of moles by the molar mass. The balanced chemical equation for acetic acid is CH3COOH, with a molar mass of 60.05 g/mol. Thus, the mass of acetic acid would be 0.023 moles x 60.05 g/mol = 1.381 g.
Therefore, the calculated molar mass of acetic acid is approximately 60.05 g/mol.
