Question

Calculate the mass of baking soda, NaHCO3, needed to neutralize 3.0mL of 3.0 M hydrochloric acid.

Answer 1

1. Write the equation.

2. Convert what you have to mols. L x M = mols.

3. Convert mols of what you have from step 2 (mols HCl) to mols of what yu want, in this case it is NaHCO3.

4. Convert mols NaHCO3 to grams NaHCO3.
mols x molar mass = grams.
Post your work if you get stuck.

Answer 2

i need help getting the equation? i missed a couple of days and im so lost

Answer 3

yea i cant get the equation either and i was there

Answer 4

Equation.
NaHCO3 + HCl ==> NaCl + H2O + CO2

simple, huh?
Don't forget to change mL HCl to L since the mol equation is M x L = mols.

Answer 5

what's the answer?

Answer 6

Show me your steps. I don't need the practice.

Answer 7

Wait, I'm confused. Why do you need the equation?

Answer 8

yall are idots!!!!
