# A #5.00*g# mass of #"sodium bicarbonate"# requires WHAT volume of #3.00*mol*L^-1# #HCl# for stoichiometric equivalence?

##### 1 Answer

We need (i) a stoichiometric equation.....and (ii) we need approx.

#### Explanation:

And thus (ii) there is 1:1 molar equivalence between hydrochloric acid and sodium bicarbonate.

Of course we are not done. We have to work out the number of moles of sodium bicarbonate and hydrochloric acid.

We know that

And we know that

So....

And given the equation, I need an equivalent quantity of

i.e.

Since there are

This does seem a lot of work. But the answer depends on the two defining equations, i.e.

Just on the relationship between

We know that
