If I have 84 grams of sodium bicarbonate and reacted with 60.1 grams of acetic acid how do I figure out the total grams of products that will be formed. I need help on how to approach this problem.

First of all, you have to write your equation. The formula of sodium bicarbonate is Na_2CO_3 and that of acetic acid, CH_3COOH

The equation is then;

Na_2CO_3 + CH_3COOH \rightarrow (CH_3COO)Na + H_2O + CO_2

- Now, balance the equation.
- Find the number of moles of sodium bicarbonate there is in 84 grams.
- Find the number of moles of acetic acid there is in 60.1 grams.
- From the equation, find the mole ratio, hence the limiting reagent.
- Take the number of moles of the limiting reagent, and with the equation, find the number of moles of each reactants produced.
- With the number of moles, you can find the mass of the products.

Hope it helped! Feel free to ask if you got lost somewhere. :)
