Question

A 130.0-g sample of a certain bronze is 90.0% copper by mass and 10.0% tin. which metal can be called the solvent, and which the solute?

Answer 1

Answer : As per the definition of solute and solvent , solute is a moiety which is usually of small concentration and solvent is which is present in large quantity.

So, in this case of 130.0 g of sample of bronze which is made up of 90% Cu by mass and 10% Sn. 

Hence, it is clear that solute is 10.0% Tin and Solvent is 90% Copper.

Answer 2

Answer:

The copper is solvent and tin is solute.

Explanation:

Solution =  Solute + solvent

Solute is that substance in a solution which gets dissolves in a solvent. it is always present in a lessor amount than the solvent.

Where as solvent is that part of solution in which solute gets dissolved.It is always present in a larger amount than that of the solute.

Mass of the sample = 130.0 g

Percentage of copper by mass = 90.0%

Mass of copper = $\frac{90.0}{100}\times 130.0 g=117.0 g$

Percentage of tin by mass = 10.0%

Mass of tin= $\frac{10.0}{100}\times 130.0 g=13.0 g$

Since mass of copper is larger than that of tin which makes copper a solvent and tin a solute.
