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:
dentifying genetic variants Genome sequencing has the potential to improve the diagnosis of conditions caused by changes in the DNA and indicate what treatments may be most effective. Importantly, it may also red-flag treatments likely to cause adverse reactions.
Explanation:
Through hypothesis and experiments
The products are on the right side of the chemical equation, while the reactants are on the left side of the chemical equation.
Therefore if we have:
methane + oxygen → carbon dioxide + water
Then the reactants are methane + oxygen
The products are: A) Carbon dioxide + Water
