3. The density of acetic anhydride is 1.08 g/mL. How many moles of acetic anhydride are used in this experiment
1 answer:
Answer:
Number of moles = 0.1058 mol
Explanation:
Density = 1.08 g/mL
Volume = 10ml
Density = Mass / Volume
Mass = Density * Volume
Mass = 1.08 * 10 = 10.8g
The molar mass of acetic anhydride = 102.09 g/mol
Molar mass = Mass / Moles
Upon solving for moles;
Moles = Mass / Molar mass
Moles = 10.8 / 102.09 = 0.1058 mol
