A 32mL solution of 2.7M NaCL is mixed with 83mL of 1.8M HCL. What is the molaritt of the CL in the new solution.
Thank you for your help
calculate the percent my mass of zinc in the post-1982 penny using the following information: total mass of each penny is 2.500g, density of copper is 8.96g/ml, density of zinc is 7.14g/ml and the mass of a penny if it were 100% copper would be 3.11g
mols Cl in HCl = M x L = ?
mols Cl in NaCl = M x L = ?
Add mols to obtain total mols Cl.
Add L to obtain total volume.
M Cl = total mols/total L = ?
Calculate the resulting molarrity when 150ml of 0.450m Nacl solution is mixed with 100ml of 2.50m Nacl solution?
To find the molarity of Cl- in the new solution, we need to calculate the moles of Cl- present in both the NaCl solution and the HCl solution, and then add them together to get the total moles of Cl-. Then, divide the moles of Cl- by the total volume of the new solution (the sum of the volumes of NaCl and HCl) to obtain the molarity.
Let's calculate the moles of Cl- in the NaCl solution first:
Moles of NaCl = Volume of NaCl solution (in liters) x Molarity of NaCl
Moles of NaCl = 32 mL x (1 L / 1000 mL) x 2.7 M NaCl
Next, calculate the moles of Cl- in the HCl solution:
Moles of HCl = Volume of HCl solution (in liters) x Molarity of HCl
Moles of HCl = 83 mL x (1 L / 1000 mL) x 1.8 M HCl
Now, sum the moles of Cl- from both solutions:
Total moles of Cl- = Moles of NaCl + Moles of HCl
Finally, calculate the molarity of Cl- in the new solution:
Molarity of Cl- = Total moles of Cl- / Total volume of the new solution (in liters)
Total volume of the new solution = Volume of NaCl solution (in liters) + Volume of HCl solution (in liters)
Using these calculations, you can find the molarity of Cl- in the new solution.
