Concentration & Volume Calculations Involving Equations
This is part of Year 11 HSC Chemistry course under the topic of Molarity.
HSC Chemistry Syllabus
relate stoichiometry to the law of conservation of mass in chemical reactions by investigating:
– balancing chemical equations (ACSCH039)
– solving problems regarding mass changes in chemical reactions (ACSCH046)
- Manipulate variables and solve problems to calculate concentration, mass or volume using:
Concentration and Volume Calculations Involving Equations
The reaction between nitric acid and potassium produces potassium nitrate and hydrogen gas.
What volume of a 0.250 mol L–1 solution of nitric acid is required to completely react with 15.0 g of potassium?
43.50 mL of a 0.100 mol L–1 solution of sodium hydroxide is required to completely react with a 25.00 mL hydrochloric acid solution.
Calculate the concentration of the hydrochloric acid solution.
Excess calcium carbonate is added to a 500.0 mL solution of hydrochloric acid to produce calcium chloride, carbon dioxide and water.
If 2.20 mol carbon dioxide is produced, what was the concentration of the hydrochloric acid solution?
