The answer would be B) Lower, because pure water freezes at 32 degrees Fahrenheit whereas salt water freezes at 28.4 degrees Fahrenheit. Hopefully this helps!

Answer:

Freezing point of seawater is lower as compared to pure water

Explanation:

Seawater contains salts like MgCl_{2}, NaCl etc.

According to colligative properties of molecules, presence of solute in a pure solvent lowers freezing point of pure solvent obeying the following equation-

                                        \Delta T_{f}=k_{f}.m

where \Delta T_{f} is lowering of freezing point, k_{f} if cryogenoscopic constant of solvent and m is molality of solution.

In seawater, water is the solvent and MgCl_{2}, NaCl etc are solutes.

Hece freezing point of seawater is lower than pure water

Sylvanite is a mineral that contains 28.0% gold by mass. How much sylvanite would you need to dig up to obtain 73.0 g of gold?
Scorpion4ik [409]

You would have to dig up 261 g of sylvanite.

Mass of sylvanite = 73.0 g Au × (100 g sylvanite/28.0 g Au) = <em>261 g</em> sylvanite.
