Assuming the molar mass of oxygen is 18.01, you only need 16 grams (B) of oxygen because the molar mass of hydrogen is about 1 gram.
16+1+1=18

Ammonium perchlorate appears as a white, crystalline solid or powder. Classified as a division 1.1 explosive if powdered into particles smaller than 15 microns in diameter or if powdered into larger particles but thoroughly dried. Does not readily burn, but will burn if contaminated by combustible material. May explode under prolonged exposure to heat or fire. Used to make rocket propellants, explosives, pyrotechnics, as an etching and engraving agent, and in analytical chemistry.

One liter of a solution is found to contain 0.022 moles of HCl. Calculate the pH of the solution. Assume complete dissociation.

Ierofanga [76]

Answer:

The pH of the solution is 1.66

Explanation:

Step 1: Data given

Number of moles HCl = 0.022 moles

Molar mass of HCl = 36.46 g/mol

Step 2: Calculate molarity of HCl

Molarity HCl = moles HCl / volume

Molarity HCl = 0.022 moles / 1 L = 0.022 M

[HCl] = [H+] = 0.022 M

Step 3: Calculate pH

pH = -log [H+]

pH = -log(0.022)

pH = 1.66

The pH of the solution is 1.66
