What made of a 40.0% NaOH solution should be diluted to 1.00 L with water to prepare a solution that is 0.10 M in NaOH?
30) If 176 mL of 1.00 M NaOH is diluted to 1.00 L, what is the molarity of the resulting solution? (YOU MUST SHOW YOUR WORK ON ATTACHED SHEETS) PLACE ANSWER HERE
you want to titrate a 0.10 l of 0.20 m naoh. However, you are given a 0.50 l solution of h3po4 of unknown concentration. It takes 0.25 l solution of 0.25 L solution of 0.25 m Ca(oh)2 to neutralize the H3Po4 solution. Find the concentration of the h3po4 solution and then calculate how many litres of the original h3po4 solution is needed to fully neutralize the naoh solution
If 166 mL of 1.00 M NaOH is diluted 1.00 L, what is the molarity of the resulting solution? Please show all work. Please use sig figs in calculations. Please use units in calculations. :)
