I hope I have answered your question. Have a nice day ahead.
Answer:
1.3 kg
Explanation:
Mass of ocean water = mass of NaCl × (mass of ocean water/mass NaCl).
The % NaCl tells us there are 3.5 g NaCl/100 g ocean water or 100 g ocean water/3.5 g NaCl.
Mass of ocean water = 46.8 × (100/3.5)
Mass of ocean water = 46.8 × 28.6
Mass of ocean water = 1300 g = 1.3 kg
<em>Note</em>: The answer can have only <em>two significant figures</em> because that is all you gave for the percentage of NaCl.
Answer:
Electrons are a type of subatomic particle with a negative charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron
