5.2mL
How many mols do you need? That's mols = M x L = 0.48 x 0.1235 L = ?
Then M = mols/L soln. Substitute. Solve.
You know M = 5.00 and you know mols from above. Solve for L and convert to mL.
Then M = mols/L soln. Substitute. Solve.
You know M = 5.00 and you know mols from above. Solve for L and convert to mL.
