How many moles of water, H2O, are present in 75.0 g H2O? Mole Concept: The mass of one mole of an element or a compound is equal to the mass number of the molecule expressed in the units of a gram. We can find the moola mass of a compound or an element from the molecular formul...
When 60 grams of Na2O2 reacts with 30 grams of H2O, what is the limiting reactant? Na2O2 + H2O arrow NaOH + H2O2 How many grams of the excess reactant remain when 2.66 moles of NaOH and 1.40 moles of CO2 are allowed to r...
How many moles of Mg are in 92.3 grams of Mg? Division Rule for Moles: The mass of an element is measured in grams and we'll divide the number of grams by the grams per mole value of an element for the required moles of an element. Here, we have: {eq}n\propto m\\[2ex] ...
Converting From Mass to Moles Calculate the number of moles of water in 600 grams of water (H2O). Find hydrogen and oxygen on the periodic table. Set up the following equation relating grams to moles: x moles H2O = (1 mole H2O/18 grams H2O) x (600 grams H2O) Solve the equation in ...
