Answer 1

Answer:

3.5 × 10⁵ g of salt

Explanation:

What is the mass (grams) of salt in 10.0 m³ of ocean water?

We have this data:

• 1.000 mol salt is equal to 58.44 g salt
• 1.0 L of ocean water contains 0.60 mol of salt

We will need the following relations:

• 1 L = 1dm³
• 1 m³ = 10³ dm³

We can use proportions:

$10.0m^{3} .\frac{10^{3}dm^{3} }{1m^{3} } .\frac{1L}{1dm^{3} } .\frac{0.60molSalt}{1.0L} .\frac{58.44gSalt}{1molSalt} =3.5 \times 10^{5} gSalt$
