What is the molarity of an aqueous solution containing 21.7 g of glucose (C6H12O6) in 1.2 L of solution?
A solution is created by adding 0.05 moles of H2CO3 (3.1 g, total mass) to 5-L of water, resulting in a pH of 4.2. Now, we add sodium hydroxide (NaOH, strong base) until the pH reaches 7. You can neglect any changes in volume. What is the alkalini..
