Answer to: How do you find the number of moles of a gas if the pressure is 1.00 atm, the volume is 800 L, the temperature is 325 K, and KE = 4.05...
The yield of the product is calculated using the mole to mole ratio between the reactants and products. The mole to mole ratio is equal to the ratio between the stoichiometric coefficients of reactants and products. Answer and Explanatio...
How to use a balance to find the mass of an object? Explain. Any property of matter that becomes evident during a chemical reaction can only be measured by what aspect of a substance? Let's say your substance has a mass of 145 grams and a volume of 63 ml. Knowing th...
Learn how to find the molarity of a solution or the moles of gas in a given volume using stoichiometry. See examples of calculating moles from molarity. Related to this QuestionHow many grams of ethanol, C_2H_6O, are required to produce a 250 mL solution at 1.8...
To find the molar mass of the solute, refer to a periodic table. If the solute is a single element, calculate the molar mass of that element. If it consists of a more than one element (i.e. a compound) calculate the molar mass of the compound. Every element has a different molar ...
In summary, using the ideal gas law, we can determine the number of moles of gas in a 7.71 liter vessel at a temperature of 18.6oC and a pressure of 8.35 atm. We can use the formula # of moles = (pressure * volume) / (gas constant * temperature) to find that t...
To find the molar mass of a compound, you need to add the molar mass of all the elements in that compound. Take a look at NaOH which contains sodium, oxygen and hydrogen. The molar mass of sodium is 22.99 g/mol, oxygen is 15.999 g/mol, and hydrogen is 1.008 g/mol. ...
Re: How do you calculate the molar mass? « Reply #8 on: February 18, 2008, 09:49:07 PM » Just for the record, when you have H20 trapped like that, it's called a hydrate. Just a little snippet of info that might be useful to you sometime Logged Print...
To calculate the number of atoms in a formula, the weight of a sample, its atomic mass from the periodic table and a constant known as Avogadro's number are needed. Step 1: Find the Molar Mass of the Formula Find a periodic table of elements to find the molar mass of your sample. ...
Note that the mass number is equal to the mass (in grams) of one mole of lithium; this is the molar mass of lithium.Determine the Molecular Mass of a Chemical Compound Step 1 Determine the molecular mass of carbon dioxide (chemical formula CO2). Find carbon and oxygen on the periodic ta...
