Question

Seawater is typically 3.5% salt and has a density of 1.03 g/mL. How many grams of salt would be needed to prepare enough seawater solution to completely fill a 62.5 L tan

Answer 1

Amount of salt needed is around 2.3*10³ g

Step-by-step explanation:

The salt content in sea water = 3.5 %

This implies that there is 3.5 g salt in 100 g sea water

Density of seawater = 1.03 g/ml

Volume of seawater = volume of tank = 62.5 L = 62500 ml

Therefore, the amount of seawater required is:

`=Density*Volume = 1.03g/ml*62500ml = 6.44*10^(4) g`

The amount of salt needed for the calculated amount of seawater is:

`=(6.44*10^(4)g\ water*3.5g\ salt )/(100g\ water) =2254 g =2.3*10^(3) g`
