For example, this equation is also balanced if we write it as, The ratio of the coefficients is 4:2:4, which reduces to 2:1:2.

However, the equation is balanced as long as the coefficients are in a 2:1:2 ratio. "contentUrl": "https://slideplayer.com/slide/12860497/78/images/6/Item+Number+Mass+%28g%29.jpg", We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The calculated value makes sense because it is almost four times times the mass for 1 mole of aluminum. 2.5 mol Kr x 6.022x1023 atoms Kr = 1.5 x 1024 atoms. \[\ce{NH_4NO_3} \left( s \right) \rightarrow \ce{N_2O} \left( g \right) + 2 \ce{H_2O} \left( l \right) \nonumber\].

Ammonium nitrate decomposes to dinitrogen monoxide and water according to the following equation. "@type": "ImageObject", }, 15 Sequentially, the process is as follows: This three-part process can be carried out in three discrete steps or combined into a single calculation that contains three conversion factors. "name": "Would you like a mole of $", Stated mathematically. For the reaction in which hydrogen and oxygen combine to make water, for example, we can construct the following ratios: \[\mathrm{\dfrac{2\: mol\: H_2}{1\: mol\: O_2}\: or\: \dfrac{1\: mol\: O_2}{2\: mol\: H_2}}\], \[\mathrm{\dfrac{2\: mol\: H_2O}{1\: mol\: O_2}\: or\: \dfrac{1\: mol\: O_2}{2\: mol\: H_2O}}\], \[\mathrm{\dfrac{2\: mol\: H_2}{2\: mol\: H_2O}\: or\: \dfrac{2\: mol\: H_2O}{2\: mol\: H_2}}\]. We also established that 1 mol of Al has a mass of 26.98 g (Example). We can use that ability to answer stoichiometry questions in terms of the masses of a particular substance, in addition to moles. "@type": "ImageObject", We can divide both sides of this expression by either side to get one of two possible conversion factors: \[\mathrm{\dfrac{1\: mol\: Al}{26.98\: g\: Al}\, and\, \dfrac{26.98\: g\: Al}{1\: mol\: Al}} \label{Eq1}\], The first conversion factor can be used to convert from mass to moles, and the second converts from moles to mass.

We have used balanced equations to set up ratios, now in terms of moles of materials, that we can use as conversion factors to answer stoichiometric questions, such as how many moles of substance A react with so many moles of reactant B. How many moles of Al2O3 will be produced when 23.9 g of H2O are reacted according to this chemical equation? Here, we will extend the meaning of the coefficients in a chemical equation.
