Splet04. jul. 2024 · Engineers use conservation of mass, called a “mass balance,” to determine the amount of product that can be obtained from a chemical reaction. Mass balance … SpletIf the masses of reactants and products of a reaction are known then we can use them to write a balanced equation for that reaction This is done by converting the masses to moles and simplifying to find the molar ratios Worked Example Example 3 A student reacts 1.2 g of carbon with 16.2 g of zinc oxide. SpletStep 3: Convert moles of other reactant to mass We were asked for the mass of \ce {NaOH} NaOH in grams, so our last step is to convert the 6.32 \times 10^ {-2} 6.32 ×10−2 moles of \ce {NaOH} NaOH to grams. We can do so using the molar mass of \ce {NaOH} NaOH ( \pu {40.00 g/mol} 40.00 g/mol ): pure chess - playstation 4
