you dissolve 0.70 moles of HCI in enough water to prepare 250ml of solution. what is the molarity of the solution you have prepared
2.8 M
M = mols/L soln
M = 0.70 mols/0.250L = ?
Well, well, well, let's do some clown math here! To find the molarity, we need to divide the number of moles by the volume of the solution in liters. So, let's get the party started!
First, we need to convert the volume from milliliters to liters. We have 250 mL, so that's 0.25 liters (because there are 1000 milliliters in a liter).
Now, we divide the number of moles by the volume in liters. We have 0.70 moles of HCI divided by 0.25 liters, which gives us a molarity of **2.8 M**. Ta-da!
Just remember, if you need any more clown-tastic answers or jokes, I'm here to amuse you!
To find the molarity of a solution, you need to know the number of moles of solute (in this case, HCl) and the volume of the solution in liters.
Given:
- Moles of HCl (solute): 0.70 moles
- Volume of solution: 250 mL (or 0.250 L)
Molarity (M) is defined as moles of solute divided by liters of solution. To find the molarity, you can use the formula:
Molarity (M) = Moles of solute / Volume of solution (in liters)
Plugging in the given values:
Molarity (M) = 0.70 moles / 0.250 L
Performing the division, we get:
Molarity (M) = 2.8 moles/L
Therefore, the molarity of the solution prepared is 2.8 M.
To find the molarity of a solution, you need to know the number of moles of solute (HCI) and the volume of the solution in liters.
Given:
Number of moles of solute (HCI) = 0.70 moles
Volume of the solution = 250 ml
First, you need to convert the volume from milliliters (ml) to liters (L). There are 1000 milliliters in a liter, so:
Volume = 250 ml ÷ 1000 = 0.250 L
Now you can calculate the molarity (M) using the formula:
Molarity = moles of solute ÷ volume of solution in liters
Molarity = 0.70 moles ÷ 0.250 L
Molarity = 2.8 M
Therefore, the molarity of the solution you have prepared is 2.8 M.
