To find the mass of a one mole of a specific molecule, add the atomic masses of each of its component atoms. You can look these up in the periodic table.
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, with the omission of a subscript signifying "1." There are t...
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
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...
The molar mass is: 23 + 16 + 1.008 = 40.008 g Thus, the equivalent weight is 40.008g/1 or 40.008 g/equivalent. What is the difference between equivalent weight and molecular weight? Molecular weight is the total atomic mass of a molecule for a compound. Equivalent weight, on the other...
Add these values together foreach different atomin the molecule. This will give you themolecular massof the molecule. This is equal to the number of grams in one mole of the substance. Divide the number of grams of thesubstanceby the molecular mass. ...
Calculate the molarity of a 5% glucose solution. How many grams of glucose (C6H2O6 molecular mass=180 daltons) would be present in one liter of a 1M (molar) solution of glucose? To prepare a 248 mM sugar solution, how many sugars (molecular weight = 309 g/mol...
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
Calculate the molecular weight of the lightest gas, that could theoretically be a significant part of Earth's atmosphere. Ignore the question of whether or not a gas with this molecular weight actually exists. At STP, 0.237 L of a gas weighs 0.460 g. Calculate the molar mass of the gas....
