Ocean water contains 3.5 % nacl by mass. what mass of ocean water in grams contains 46.8 g 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,

M - mass of ocean water

W - mass of NaCl

m - mass % of the NaCl

Put the values in the formula,

Therefore, the mass of ocean water is 1300g or 1.3 kg.

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.
