How Much NaOH Is Contained In 89.0 ML Of A 1.80 M Solution Of NaOH In H₂O?Answer In Units Of Mol.
Introduction
In chemistry, understanding the concentration of a solution is crucial for various applications, including chemical reactions, laboratory experiments, and industrial processes. Concentration is typically expressed in terms of molarity (M), which is defined as the number of moles of solute per liter of solution. In this article, we will explore how to calculate the amount of NaOH (sodium hydroxide) contained in a given volume of a solution.
Understanding Molarity
Molarity (M) is a measure of the concentration of a solution, expressed as the number of moles of solute per liter of solution. It is calculated using the formula:
M = moles of solute / liters of solution
For example, a 1.80 M solution of NaOH means that there are 1.80 moles of NaOH per liter of solution.
Calculating the Amount of NaOH
To calculate the amount of NaOH contained in 89.0 mL of a 1.80 M solution, we need to follow these steps:
- Convert the volume from milliliters (mL) to liters (L). There are 1000 mL in 1 L, so:
89.0 mL = 0.089 L
- Use the formula for molarity to calculate the number of moles of NaOH:
moles of NaOH = M x liters of solution = 1.80 M x 0.089 L = 0.1602 mol
Therefore, 89.0 mL of a 1.80 M solution of NaOH contains approximately 0.1602 mol of NaOH.
Conclusion
In conclusion, understanding the concentration of a solution is crucial for various applications in chemistry. By using the formula for molarity, we can calculate the amount of NaOH contained in a given volume of a solution. In this article, we calculated that 89.0 mL of a 1.80 M solution of NaOH contains approximately 0.1602 mol of NaOH.
