Show answer

Answer

Concentration

Show question

Question

_________ is one that has a significant amount of solute dissolved into it when compared to a _________.

Show answer

Answer

Concentrated solution; diluted solution

Show question

Question

What are solutions and solutes?

Show answer

Answer

Solutions are heterogenous mixtures or mixtures with a uniform composition.

Show question

Question

What do we use some of the concentration formulas for?

Show answer

Answer

We use the molarity equation in temperature dependent situations.

Show question

Question

Which of the following formulas do we use when both units are the same?

Show answer

Answer

mass percent

Show question

Question

What’s the molality of a solution prepared from 0.1 kg of sucrose () dissolved into 0.7 kg of water?

Show answer

Answer

Show question

Question

Find the volume percent of a solution that’s created by mixing 0.1 L of carbon dioxide and 0.9 L of nitrogen.

Show answer

Answer

Show question

Question

Find the concentration of a solution that contains 2 g of carbon dioxide dissolved in, 10,000 g water.

Show answer

Answer

You can use ppm just multiply by 10^6 instead and you'll get 199.96 ppm. If you use any other part per x formula just multiply accordingly.

Show question

Question

What's the difference betwen molarity, molality, and mole fractions?

Show answer

Answer

Mole fractions are used for dimensionless quantities, while molarity has units of mol/L and molality has units of mol/kg. In addition, mole fractions are also primarily used for gases.

Show question

Question

For this problem, please just identify what formula you would use to solve it.

Problem:

Find the composition of hydrogen in a gas that contains X moles of hydrogen in Y moles of nitrogen to form ammonia.

Show answer

Answer

Show question

Question

For this problem, please just identify what formula you would use to solve it.

Problem:

Find the percentage of X g sucrose dissolved in Y g of water.

Show answer

Answer

Even though it doesn't say find the mass percentage, the only things you are given are X g and Y g of solute and solution respectively. Thus, it would only make sense for you to use mass percent.

Show question

Question

For this problem, please just identify what formula you would use to solve it.

Problem:

Find the percent of a solution that’s created by mixing X liters of helium and Y liters of nitrogen.

Show answer

Answer

Even though the question doesn't specify for us to find the volume percent, we're only given X and Y liters of two different gases. Thus, we can only use volume percent to find the concentration.

Show question

Question

What are some of the concentration formulas that we can use when the solution is very dilute?

Show answer

Answer

From the table given above and in the article, we can see that we can use the ppth, ppm, ppb, and even ppt formulas in these cases.

Show question

Question

What are solvents?

Show answer

Answer

A solvent is the substance in which another substance, the solute, dissolves into to form a solution.

Show question

Question

When you are given the mass of a solute and the volume of a solution what is the easiest concentration formula to use?

Show answer

Answer

The answer is the mass concentration formula because we're given exactly the two components needed to find it.
