How many grams will remain after 98.0 days if Phosphorus-32 has a half-life of 14.0 days Starting with 6.00g of ,?
Consider the titration of 100.0 mL of 0.110 M NaOH with 1.00 M HBr. Find the pH at the following volumes of acid added and make a graph of pH versus Va: Va= 0,2,5,8,10,10.1,11,11.1, and 12 mL Compute Ve, first.
The numbers above are also the only numbers I am given. I do not have delta G's of molar G's. If you have an answer that solves for the G's and shows me step by step how to solve the problem, you will get five stars.
