Answer:
44
Explanation:
Given that :
Mass of solute = Mass of urea = 16g
Mass of water = 20g
Mass of solution = (mass of solute + mass of solvent) = (mass of urea + mass of water) = (16g + 20g) = 36g
Percentage Mass = (mass of solute / mass of solution) * 100%
Percentage Mass = (16 / 36) * 100%
Percentage Mass = 0.4444444 x 100%
Percentage Mass = 44.44%
Percentage Mass = 44%
Mhm, it keeps the planets in place and circle around the Sun's gravitational pull, like how the Earth's small-like gravitational pull keeps the moon to circle around our planet, and as a perk it makes the 80% water that around this whole place to have high and low tides.

Explanation:
In the scientific method, you always begin with asking a question. Then, you do research, make a hypothesis, and test that hypothesis based on the initial question. If experimental data does not support your hypothesis, then you can restart by asking a new question, based on what you already know. Hope this helps!
It is indeed true. Molecular Polarity occur in covalent bonds. Like the water molecule h20
