Grams From,41
How many grams of sodium hydroxide can be produced from 41.6 g of calcium hydroxide according to this ???
How many grams of sodium hydroxide can be produced from 41.6 g of calcium hydroxide according to this equation?
Ca(OH)2 + Na2CO3 → 2NaOH + CaCO3
EX13
g??
When in doubt convert to the mole!
41.6g Ca(OH)2* [1 mol Ca(OH)2/ 74g Ca(OH)2] grams cancel.
* [2 mol NaOH/1 mol Ca(OH)2] moles of Ca(OH)2 cancel.
* [40 g NaOH/ 1mole NaOH] = 44.97 g NaOH.
The grams of Ca(OH)2 you get by adding up the weight fromthe periodic table. When you get it into moles, you use the equation to see how many moles of NaOH there are for every mole of Ca(OH)2. In the next step, you use the periodic chart again to find the weight of NaOH to cancel out the moles.
