Given the following balance equation, CH_4 + 2O_2 to CO_2 + 2H_2O How many grams of CO_2 can be made from 1 mole O_2? Butane, C4H10 , reacts with oxygen, O2 , to form water, H2O , and carbon dioxide, CO2 , as shown in...
mole × molecular weight = mass (rearrange the equation) mass = molecular weight × mole As 1.626×1023 molecules of NaOH is also equal to 0.27 moles, and we know that the molecular weight of NaOH is 40, we can use these numbers to get: mass = 40 × 0.27 = 10.8 g So we now know...

Dividing and multiplying the right-hand side by the total number of moles, n, and invoking Equation (6.4) defines the average molecular weight, that is, (6.5)M=mn=x1M1+x2M2+⋯ The mass fraction of component i is defined as follows: (6.6)mfi=niMin1M1+n2M2+⋯ormfi=xiMix1M1+x2M2...
This conversion is useful because most chemicals are stored and measured either by weight (g) or volume (L). However, most chemical equations are written in terms of moles so that the number of atoms of each type balances out on both sides of the equation. ...

To calculate the number of moles of a compound you have on hand, you divide the mass by the mass of one mole of the compound, which you can calculate from the periodic table.Using the Mole Fraction Equation The mole fraction formula is particularly easy to understand and use if you ...
