Question

how many grams of sodium, hydrogen, carbon, and oxygen are presented in a one-pound (454g) box of baking soda (sodium bicarbonate)?

Answer 1

Do you have any answer choices?

Answer 2

Sodium bicarbonate is NaHCO3

Divide 454g by the molar mass of sodium bicarbonate to get moles

Now, looking at the formula, for each mole of sodium bicarbonate you have 1 mol Na, so moles of Na = moles sodium bicarbonate from the previous step

From there, multiply (moles Na)(molar mass of Na) to get grams Na

Repeat with the other elements
