## What are mixture problems?

Table of Contents

Mixture problems are ones in which two different solutions are mixed together, resulting in a new, final solution. Using a table will help to set up and solve these problems.

**How do you deal with a mixture problem?**

The way to solve most mixture problems is to treat them like other rate problemsâ€”identify variables, create equations, and make tables to organize the information and highlight ways to solve the problem.

### How do you find the percentage of a mixture?

Mass percent is a method of expressing the concentration of a substance in a mixture or element in a compound. It is calculated as the mass of the component divided by the total mass of the mixture and then multiplied by 100 to get the percent.

**How much of a 20% acid solution would a chemist have to mix with one liter of a 40% acid solution to yield a 36% acid solution?**

250 milliliters

How much of a 20% acid solution would a chemist have to mix with one liter of a 40% acid solution to yield a 36% acid solution? The chemist must add 250 milliliters of the 20% acid solution.

#### What is a solution problem?

countable noun. A solution to a problem or difficult situation is a way of dealing with it so that the difficulty is removed.

**Can you add concentrations together?**

In general when your are mixing two different concentrations together first calculate number of moles for each solution (n=CV ,V-in liter) then add them together it will be total moles,then concentration of mixture will be = total moles / total volume(liter).

## How do you find the final concentration of a mixture?

Divide the number of moles present by the total volume of the mixture. The resulting value will be the molar concentration. The resulting equation for our example would be (2 moles / 0.5 L = 4 M). The molarity of concentrations is abbreviated by the letter M.

**How many liters of a 30% alcohol solution must be mixed with 50 liters of a 90% solution to get a 50% solution?**

1 Expert Answer That means you need 45 liters of the 30% solution.
