Answer:

  • Mass of the glass is 270 g when empty

Explanation:

Find the difference in two masses, this will give us is the mass of water in half-filled glass:

  • 750 - 510 = 240 g

Now find the mass of the glass by the difference of half-filled glass with water and just water mass of same level:
