In a reaction A+B--->C, reactant A has 5g of product C has 9g of product. How many grams should reactant B contain?
1 answer:
According to the law of conservation of Mass:
In a chemical reaction mass can neither be created nor be destroyed
So, we can say that: Mass of A + Mass of B = Mass of C
In the given reaction,
One of the reactants weigh 5 grams and another one weighs x grams
The mass of the product of this reaction is 9 grams
<u>Mass of reactant B: </u>
Mass of A + Mass of B = Mass of C
5 + x = 9
x = 4 grams
