From the balanced chemical equation, calculate the moles of NH 3 that reacted with HCl. From the equation, 1 mol HCl reacts with 1 mol NH 3 So, 2.85 ? 10 -3 mol HCl had reacted with 2.85 ? 10 -3 mol NH 3 in the cloudy ammonia solution.

Let’s begin by choosing a simple quantitative problem requiring a single measurement—What is the mass of a penny? As you consider this question, you probably recognize that it is too broad. Are we interested in the mass of a United States penny or of a Canadian penny, or is the di?erence relevant? Because a penny

The most common type of balance is an in which the balance pan is placed over an electromagnet. Another type of analytical balance is the mechanical balances which are replaced by the electronic balances. electronic balance electronic balance Equipment for Measuring Volume Analytical …
