temperature increase because burning causes heat therefore the planet heats up from all the fossil fuels burned aka "global warming"
If i’m correct it’s b, bouyance force.
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.
