calculate the mass in grams of 2.6 mole of baking soda, NaHCO3?

Question

plz help!!

Answer 1

First figure out the moleculear weight of the material

1(23) + 1(1) + 1(12) + 3(16) = M (grams / mole)
understand what the above means and how I developed it; you do the calculation.

now let's do some algebra on units

remember
x (y/x) = y therefore

(mole) (grams/mole) = grams

Therefore

(2.6 moles) (M grams / mole) = 2.6 M grams

you do the calc and understand what is going on

You need to understand how to use units and all will fall in place.
