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
Note: The answer can have only two significant figures because that is all you gave for the percentage of NaCl.
Mass is the measure of atoms or molecules in a chemical entity. The mass of ocean water is 1300g or 1.3 kg.
Mass:
It is the measure of atoms or molecules in a chemical entity. It is measured in ( Kilogram)kg.
Given here,
The mass of NaCl = 46.8g
The % mass of NaCl in ocean water is 3.5%(w/v)
The mass of ocean water can be calculated using the formula,
[tex]\bold{M = W (\frac{100}{m} )}[/tex]
M - mass of ocean water
W - mass of NaCl
m - mass % of the NaCl
Put the values in the formula,
[tex]\bold{ M = 46.8 (\frac{100}{3.5} )}\\\\\bold{ M = 1300}\\[/tex]
Therefore, the mass of ocean water is 1300g or 1.3 kg.
