In a solution, there is 1 g of NaCl for every 5 g of water.

What is the ratio of sodium to water?

A) 1NaCl: 6H2O, because the mass of the solution equals 1 g of NaCl
B)1NaCl : 5H2O, because in the solution, for every 1 g of NaCl there are 5 g of H2O
C)6NaCl : 1H2O, because the total mass of the solution will be 1 g of H2O
D)5NaCl : 1H2O, because in the solution, for every 5 g of H2O there is 1 g of NaCl

B?

To determine the ratio of sodium to water in the given solution, we need to compare the amount of NaCl (sodium chloride) to the amount of water. We are told that there is 1 g of NaCl for every 5 g of water in the solution.

To express this ratio, we need to consider the ratio in terms of NaCl and water. The correct ratio should have NaCl and water expressed in the same units.

Let's go through the options:

A) 1NaCl : 6H2O - This option has different units for NaCl and water. We cannot compare 1 g of NaCl with 6 g of H2O directly. This is not the correct ratio.

B) 1NaCl : 5H2O - This option correctly expresses the ratio in terms of the given units (grams). For every 1 g of NaCl, there are 5 g of H2O. This is the correct ratio.

C) 6NaCl : 1H2O - This option also has different units for NaCl and water. We cannot compare 6 g of NaCl with 1 g of H2O directly. This is not the correct ratio.

D) 5NaCl : 1H2O - This option has different units for NaCl and water. We cannot compare 5 g of NaCl with 1 g of H2O directly. This is not the correct ratio.

Therefore, the correct ratio of sodium to water in the solution is 1NaCl : 5H2O, as stated in option B.
