We can use this method to calculate the theoretical yield of hydrogen and oxygen that is used to produce H2O. The first step is to set up a balanced chemical equation: 2H2+O2→2H2O The second step is to find the molar mass of the reactants and the products: Molar mass of H2 = 2.0...
Step 3: Find how many moles of each ion will be present in 1 liter of the solution at equilibrium if xmolL of the compound dissolves to reach equilibrium. Since 1 mole of Ag2S dissolves into 2 moles of Ag1+ and 1 moles of S2−, xmolL of Ag2S at equilibrium would yield 2xmolL...

Measure the amount of gas used per hour by monitoring your gas meter. Calculate the amount of gas used over a 24-hour period of time and divide it by 24 to obtain the average cubic feet of gas used per hour. Step 2 Write down the heat production from a cubic foot of the fuel you...
Compounds are weighed using scales to yield grams. It's often necessary to convert grams to moles for chemistry calculations.Peter Muller / Getty Images Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion ...
Key Takeaways: How to Calculate Density Density is how much matter is contained within a volume. A dense object weighs more than a less dense object of the same size. An object less dense than water will float on it; one with greater density will sink. ...
