At standard temperature and pressure, ml = grams for water, so at STP, 134.63 ml of water = 134.63 grams.
how would you find the mass of 250 mL of water
Find the mass of an empty container using a balance. Fill the container with 100 ml of water and measure the mass again, The difference between the two measurements is the mass of 100 ml of water.
The mass of 120 mL of water is 120 g.
The mass of 100 mL of water is 100 g.
The mass of 82 mL of water is 82 g.
The mass of 10 mL of water is 10 g.
The mass of 1258 mL of water is 1258 g.
At 4 degrees C, 175 ml of pure water would have mass of 175 g.
The mass of 1 mL of water is 1 g.
The mass of 1 mL of water is 1 g.
The mass of 100 mL of water is 100 g.
Somehow your data doesn't add up. The mass difference would be 195 - 125 = 70 grams. 1 ml of water weighs roughly 1 gram, so you would expect 70 ml of water to be filled into the beaker. Your water is either contaminated, extremely heavy or its a trick question.
