P(−1.2≤z≤1.2)
A sample of oxygen at 44◦C occupies 373 mL.
If this sample later occupies 1102 mL at 60◦C
and 1.8 atm, what was its original pressure?
Answer in units of atm
Calculate the number of milliliters of solution required to provide the following:
a. 17.5 g of sulfuric acid from a 2.50 N solution in reactions that replace both hydrogen ions.
b. 24.2 g of calcium chloride from a 1.25 N solution in reactions that replace both chloride ions.
calculate the number of grams of solute necessary to prepare the following solutions:
a. 25.0 m/ of a 0.200 N sulfuric acid solution in reactions that replace both hydrogen ions.
b. 50.0 m/ of a 1.25 N phosphoric acid solution in reactions that replace all three hydrogen ions.
How many grams of magnesium hydroxide are there in 125 m/ of 3.50 N solution?
How many milliliters of 0.35 N sulfuric acid are necessary to react with 30.2 m/ of 0.52 N sodium hydroxide)
If 0.825 g of pure sodium hydroxide is titrated with 24.7 m/ of hydrochloric acid solution to a methyl orange end point, calculate the molarity and the percent by mass (density of solution= 1.02 g/ m/) of the hydrochloric acid solution.
Vinegar is a dilute solution of acetic acid. In the titration of 10.0 m/ of vinegar, 19.5 m/ of 4.20 M sodium hydroxide solution was required to neutralize tge vinegar to a phenolphthalein end point. Calculate the molarity and the percent by mass (densitu of solution= 1.01 g/ m/) of acetic acid in the vinegar.
- If 18.8 m/ of 1.25 M sodium hydroxide solution is necessary to netralized 25.0 m/ of a hydrochloric acid solution to a phenolphtalein end point, calculate the molarity and the percent by mass (density of solution= 1.02 g/ m/) of the hydrochloric acid solution.
