Calculate the number of moles of solute in 5.00 X 10^2 mL of 0.250 M HCl. Can you help me to set this problem up so that I can solve it?
Moles=volumeinliters*concentrationinM
Thank you again for your help as I was unsure how to set the problem up.
Sure! To calculate the number of moles of solute, you can use the formula:
moles = concentration (in M) x volume (in liters)
First, we need to convert the volume from milliliters (mL) to liters (L). We can do this by dividing the given volume by 1000:
5.00 X 10^2 mL ÷ 1000 = 0.500 L
Now that we have found the volume in liters, we can substitute it into the formula along with the concentration of HCl:
moles = 0.250 M x 0.500 L
Now you can multiply these values together to find the number of moles of HCl. What is the result?
Of course! To calculate the number of moles of solute, we need to use the equation:
moles = concentration (M) x volume (L)
Here, we are given the concentration of the solute HCl to be 0.250 M, and the volume is given in milliliters (mL) as 5.00 X 10^2 mL.
To solve this problem, we need to convert the given volume from milliliters (mL) to liters (L) since the concentration is given in moles per liter (M).
To convert milliliters (mL) to liters (L), we divide the volume by 1000:
5.00 X 10^2 mL ÷ 1000 = 0.500 L
Now, we can substitute the values into the formula:
moles = 0.250 M x 0.500 L
We can multiply the concentration and volume:
moles = 0.125 mol
Therefore, there are 0.125 moles of HCl in 5.00 X 10^2 mL of 0.250 M HCl.
