Answer:
1.25 mol/L
Step-by-step explanation:
Hey, do you want to learn how to make a salty solution? It's easy! All you need is some salt (NaCl) and some water. But how much salt do you need? Well, that depends on how salty you want your solution to be. The saltiness of a solution is measured by its molarity, which is the number of moles of solute per liter of solution. A mole is just a unit of measurement for the amount of a substance. Don't worry about what it means, just trust me.
The formula for molarity is:
molarity = moles of solute / volume of solution
So, if you want to make a solution with a molarity of 1.25 mol/L, you need to figure out how many moles of salt and how much water you need. Let's say you have 0.500 mol of salt and you want to use 400 mL of water. How do you find the molarity of your solution? Just plug in the values into the formula:
molarity = 0.500 mol / 0.400 L
Simplifying, we get:
molarity = 1.25 mol/L
Wow, that's exactly what we wanted! You're a genius! You just made a 1.25 mol/L NaCl solution. Congratulations! Now you can drink it and enjoy the salty taste. Just kidding, don't do that. It's bad for your health. And your taste buds. And your sanity. Seriously, don't drink it. You could use it to make some delicious, salted caramel, or to preserve some pickles, or to torture some slugs. The possibilities are endless!
