A buret is a tool designed to transfer precise amounts of liquid. A buret initially contains 70.00 milliliters (mL) of a solution, and a beaker initially contains 20.00 mL of the solution. The buret drips solution into the beaker. Each drip contains 0.05 mL of solution. After how many drips will the volumes of the solutions in the buret and beaker be equal
