Question

Lab group B determines that 0.003 moles of bicarbonate was present in their portion of an antacid tablet. How many grams of bicarbonate are in their tablet? Report your answer to 3 decimal places.

Answer 1

There are 0.183 grams of bicarbonate in their tablet

Step-by-step explanation:

Step 1: Data given

0.003 moles of bicarbonate was present in their portion of an antacid tablet

Bicarbonate = HCO3-

Molar mass of bicarbonate = 61.02 g/mol

Step 2: Calculate mass bicarbonate

Mass bicarbonate = moles bicarbonate * molar mass bicarbonate

Mass bicarbonate = 0.003 moles * 61.02 g/mol

Mass bicarbonate = 0.183 grams

There are 0.183 grams of bicarbonate in their tablet
