Mass of tablet: 1.4930g
Volume of HCL added: 100ml
Find the milimoles of HCL added
I have many questions similar to this, could someone explain how to do this...do I just find the # of moles regularly and multiply by 1000?
any help would be much appreciated
btw mililoles: mmoles right?
To find the number of millimoles (mmoles) you need the volume and concentration of HCl. So of the concentration of HCl is 0.01 M and the volume is 25 ml then the number of moles is
(25 ml /1000 ml l^-1)x(0.01 mol l^-1)moles =
which you then multiply by 1000 mmoles mole^-1 to get mmmoles = 0.25 mmoles.
It is worth noting that if you are working in ml and mole l^-1 then when you multiply ml by mole l^-1 the answer is in mmoles
Does this help?
thanks for the help!
To find the millimoles (mmol) of HCL added, you'll need to calculate the number of moles of HCL first and then convert it to millimoles. Here's how you can do it step by step:
1. Convert the mass of the tablet from grams (g) to moles (mol). To do this, you'll need to know the molar mass of the tablet's substance. Let's assume the molar mass is M grams/mol. Then, the number of moles of the tablet will be:
Moles of tablet = Mass of tablet / M
2. Next, you need to find the number of moles of HCL. This can be done using the balanced chemical equation or the stoichiometry of the reaction if you have that information. Let's assume that 1 mole of the tablet reacts with n moles of HCL. Then, the number of moles of HCL will be:
Moles of HCL = Moles of tablet × n
3. Finally, convert the number of moles of HCL to millimoles (mmol) by multiplying it by 1000. This is because 1 mole is equal to 1000 millimoles:
Millimoles of HCL = Moles of HCL × 1000
By following these steps, you should be able to find the millimoles of HCL added in the given scenario.
