In 1998, the National Institutes of Health (NIH) brought together an expert panel who recommended that body mass index be used to determine whether an individual is overweight or obese. In addition to being a fast, easy, and cheap measurement, the panelists felt that for most people, BMI w...
How do I determine the volume displaced, when given mass and volume of an object? Density = Mass / Volume = 150 kg / (30 cm * 20 cm * 500 cm). What is kg / cm^3 and explain how to use this. What is the dimensional formula of density? An object has a mass of 615 grams an...
Calculate your weight in kilograms (kg) by dividing your weight in pounds (lbs) by 2.2 to give you the "a" in the formula. This looks like: your weight (lbs) / 2.2 =a. You may need the help of a registered dietitian or healthcare professional to determine "b." But, in general, ...
In summary, to calculate the mass of gas in a tank, first measure the volume of gas in the tank. Next, determine the gas's density, which can vary with temperature and pressure. Finally, use the formula: mass = volume × density. Ensure that all measurements are in compatible units to...
Step 2: Determine the Mass of Each Individual Element Present In this step, you multiply the number of atoms in one molecule of the compound by the molar masses you collected in Step 1. The number of atoms is simply the subscript after the element's abbreviation in the molecular formula, ...
The equation to calculate density is represented with the formula density = mass / volume. To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is ...
The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents Where "n" number of equivalents is the quantity of charge depending on the substance. If the substance is an element, ion, acid, base, or ionic compound, it will determine "n". How is equivalent weigh...
Mass formula of hadrons is given for their topological structure of the junction type. The result agrees with recent candidates for baryonium. By noticing the topological structure, the OZI rule and the FWR rule are unified into a selection rule (covalence rule). This rule forbids not only ba...
Calculate the solute's formula mass by multiplying each of its elements' atomic weights by the number of that element's atoms in the solute. A mole of potassium chloride (KCl), for instance, has 1 mole of potassium, which has an atomic weight of 39.10, and 1 mole of chlorine, which ...
It is simple to determine the molar mass of elements and molecules using the periodic table, as well as convert between grams and moles. Molar Mass Calculator Common Compounds Periodic Elements Chemical Formula HCl also known as Hydrochloric Acid Molar Mass of HCl: 36.46 g/mol Element...
