The concentration of a solution containing 5 moles in 2.5 liters of solution is __________.
Understand the Problem
The question is asking for the concentration of a solution that contains 5 moles of solute in 2.5 liters of solution. To find the concentration, we can use the formula C = n/V, where C is the concentration, n is the number of moles, and V is the volume in liters.
Answer
The concentration of the solution is $2 \text{ mol/L}$.
Answer for screen readers
The concentration of the solution is $2 \text{ mol/L}$.
Steps to Solve
- Identify the variables
We have the following variables from the problem:
- Number of moles of solute ($n$) = 5 moles
- Volume of the solution ($V$) = 2.5 liters
- Use the concentration formula
We will use the formula for concentration:
$$ C = \frac{n}{V} $$
Now, substitute the values of $n$ and $V$ into the formula.
- Substitute values and calculate
Substituting the values into the formula gives us:
$$ C = \frac{5 \text{ moles}}{2.5 \text{ liters}} $$
Now, simplify this equation:
$$ C = 2 \text{ moles per liter (mol/L)} $$
The concentration of the solution is $2 \text{ mol/L}$.
More Information
Concentration is a measure of how much solute is present in a given volume of solution. In this case, we found that there are 2 moles of solute in every liter of solution. This concept is essential in chemistry and helps in determining how concentrated or diluted a solution is.
Tips
- Confusing moles with liters: Ensure to remember that moles measure the amount of substance, while liters measure volume.
- Miscalculating the division: Double-check the arithmetic steps to avoid errors in the calculation.
