Question

In the laboratory, a student dilutes 26.4 mL of a 10.5 M nitric acid solution to a total volume of 250.0 mL. What is the concentration of the diluted solution? Concentration =

Answer 1

This image will help to find out the concentration of nitric acid

Equation NIV, = N2v2 can help to solve this task. Un A student diluted 26.4mL of 10. 5M nitric acid solution to a total volume of 250mL. SOUTH My xv. = M2 X V2 s au o Ni XV = N2XV2 10.5 X 26.4 = N2 X 250 10.5X2 6.4 N2 = - 250 Na = 1 108 M V Therefore, concentration of diluted so. is 1.108m tobe Moolig In the above equation 2 Ni = Ni is the known concentration of ter the solution to amulor V = V, is the known volume of solution. N₂ = Unknow conc. of the diluted soln. V2 = Total volume of diluted solution.

This image helps to find out how much(V1) 11.6M HCl acid need to dilute to make 0.1M, .5.5Ltr  HCl acid solution.

for this can problem we can use same formula Cid How many mililiter of 11.6M HCl acid solution should be used to prepare 5-50L of o 100M. HOI? same as previous soln. V M - 1.01 = Ico o mililiter. Nivo = N28205 xq ol 116 XV, -0.1 x 5500 Vi - 0:1X5500 11.6 V = 47.41 mililiter For for the preparation of the 5.50L. of olcom solution.ol.1 we need to dilute 47.41 mililiter of 11.6M Hol acid solution to a total volume of 5500 mililiters flask. los tomelor ob to Go
