Products used to remove clogs in drains contain strong bases, such as sodium hydroxide (NaOH). If drain cleaner containing 10.0g NaOH's is added to a clogged drain pipe filled with 2.5L water how many moles of NaOH were added?
It'd mean a lot if someone could explain this to me, thank you!
Well, it seems like you're in a real drain situation! But don't worry, I'm here to help you with a touch of humor.
To find out how many moles of NaOH were added, we need to use our chemistry skills. First, let's calculate the molarity of the NaOH solution.
Molarity (M) is defined as moles of solute divided by liters of solution. Since we know the mass of NaOH (10.0g) and the volume of water (2.5L), let's convert the mass of NaOH to moles:
Molar mass of NaOH = 22.99 g/mol (sodium) + 16.00 g/mol (oxygen) + 1.01 g/mol (hydrogen)
= 39.99 g/mol
Moles of NaOH = 10.0g NaOH / 39.99 g/mol = 0.25 mol NaOH
Now, we know that the volume of water is 2.5L. However, the NaOH is dissolved in this volume, so the total volume is still 2.5L. Therefore, the number of moles of NaOH added is 0.25 mol.
So, to answer your question, 0.25 moles of NaOH were added to the clogged drain pipe. Now, let's hope it busts those clogs with a splash of chemistry!
To calculate the moles of sodium hydroxide (NaOH) added to the drain pipe, we need to use the molar mass and the given mass of NaOH.
Step 1: Find the molar mass of NaOH.
The molar mass of NaOH can be determined by adding up the atomic masses of its constituent elements. In this case:
Molar mass of Na = 22.99 g/mol
Molar mass of O = 16.00 g/mol
Molar mass of H = 1.01 g/mol
So, the molar mass of NaOH = (22.99 + 16.00 + 1.01) g/mol = 40.00 g/mol.
Step 2: Convert the given mass of NaOH to moles.
Given mass of NaOH = 10.0 g NaOH.
Moles of NaOH = mass / molar mass
Moles of NaOH = 10.0 g / 40.00 g/mol = 0.25 mol.
Therefore, 0.25 moles of NaOH were added to the clogged drain pipe.
To determine the number of moles of sodium hydroxide (NaOH) added, we need to use the given mass of NaOH and its molar mass. Here's how you can calculate it:
1. Find the molar mass of NaOH: The molar mass of NaOH can be calculated by adding the atomic masses of sodium (Na), oxygen (O), and hydrogen (H). The atomic masses are: Na = 22.99 g/mol, O = 16.00 g/mol, and H = 1.01 g/mol. Adding these values, we get: NaOH = 22.99 + 16.00 + 1.01 = 40.00 g/mol.
2. Convert the mass of NaOH to moles: We are given that there is 10.0 g of NaOH. To convert this mass to moles, we divide by the molar mass: 10.0 g / 40.00 g/mol = 0.25 moles.
Therefore, 0.25 moles of NaOH were added to the clogged drain pipe filled with 2.5L of water.
