Moles conversion to mass

The problem gives the number of moles of NaHC03 and asks for a mole-to-mass conversion. First, calculate the formula mass and molar mass of NaHC03. Then use molar mass as a conversion factor, and set up an equation so that the unwanted unit cancels. 

According to the balanced equation, 1 mol of product is produced per mol of reactant, so we know that 0.470 mol of isobutylene can theoretically yield 0.470 mol of MTBE. To find the mass of this MTBE, we do a mole-to-mass conversion ... 

We are given V, P, and T, and we need to use the ideal gas law to calculate n, the number of moles of helium in the tire. With n known, we then do a mole-to-mass conversion. 

From the moles of the unknown substance, determine the mass of the unknown substance using a mole-to-mass conversion. Use the molar mass as the conversion factor. 

Elements Mass-to-Mole and Mole-to-Mass Conversions... 

When doing mass-to-mole or mole-to-mass conversions, you will always use conversion factors that relate 1 mole of the species to its molar mass. These kinds of conversions are done over and over in chemistry, and you need to be able to do them with ease. 

Converting the moles of the sought species to mass a mole-to-mass conversion, mass (known) — mole (known) — mole (sought) — mass (sought)... 

Converting from moles of O2 to kilograms of O2 Combining the mole-to-mass conversion with the mass unit conversion gives... 

Mole-to-Mass Conversion Chromium (Cr), a transition element, is a component of chrome plating. Chrome plating is used on metals and in steel alloys to control corrosion. 

Mole-to-Mass Conversion for Compounds The characteristic odor of garlic is due to allyl sulfide [( 3115)25]. What is the mass of 2.50 mol of ( 3115)25 ... 

Sometimes it is more convenient to measure mass in larger or smaller units. Most analytical and academic chemists, for example, work in milligrams and millimoles of substance, whereas an industrial chemical engineer is more likely to think in kilograms and kilomoles. The mass-to-mole and mole-to-mass conversions in Step 1 and Step 3 are performed in exactly the same way. The conversion factor 44.01 g C02/mol CO2 is equal to 44.01 kg COj/kmol CO, ... 

Conversions of this type for elements and compounds are summarized above in Figure 3.2. Becoming familiar with this process now will help you a great deal, as mass-to-mole and mole-to-mass conversions will be widely used in future chapters. 

There are three basic stoichiometric calculations mole-to-mole conversions, mole-to-mass conversions, and mass-to-mass conversions. All stoichiometric calculations begin with a balanced equation and mole ratios. 

Stoichiometric mole-to-mass conversion A mole-to-mass conversion allows you to calculate the mass of a product or reactant in a chemical reaction given the number of moles of a reactant or product.
