In chemistry, mass ratio, often called "percent composition by mass," is the proportion of a particular molecule that consists of each that molecule's constituent elements. For example, water consists of 11.1 percent hydrogen (H) and 88.9 percent oxygen (O), meaning that a 1,000-gram sample...
How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s
Next, we will look at two examples of chemical formulas and we will work through how to calculate the mole ratio for these chemical formulas. In the first example, we will have the formula for sulfuric acid, and in the second example, we will have the formula for water. ...
Calculate Molarity: moles solute per liter of solution (notvolume of solvent added since the solute takes up some space) symbol: M M = moles / liter Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water?
100 = 40 per cent how to calculate the percentage of a number? to calculate the percentage of a number, we need to use a different formula such as: p% of number = x where x is the required percentage. if we remove the % sign, then we need to express the above formulas as; p/...

Allow us to throw in a bit of a curve ball here by reminding you that if you want to calculate the density of pixels on your screen, this is not the calculator you are looking for; try PPI calculator instead. Density formula Another way to calculate the weight to volume ratio of an ...
Chemistry question. Amphetamine (C9H13N) is a weak base with a pKb of 4.2. Calculate the pH of a solution containing an amphetamine concentration of 230 mg/L. A solution with a pH of 9 has EXACTLY how many H+ ions compared to a ...
