what mass of K2SO4 would you measure out to prepare 350 mL of a .76 M solution? The gram formula mass of K2SO4 is 174.2 g/mol
To find the mass of K2SO4 needed to prepare the solution, we can use the formula:
Mass = Concentration (M) x Volume (L) x Molar Mass (g/mol)
Given:
Concentration (M) = 0.76 M
Volume (L) = 0.35 L
Molar Mass (g/mol) = 174.2 g/mol
First, convert the volume from milliliters (mL) to liters (L):
0.35 L = 350 mL / 1000 = 0.35 L
Now, substitute the values into the formula:
Mass = 0.76 M x 0.35 L x 174.2 g/mol
Mass = 0.76 x 0.35 x 174.2 = 44.724 g
Therefore, you would measure out approximately 44.724 grams of K2SO4 to prepare 350 mL of a 0.76 M solution.
