1) Provide at least two problems(provide specific examples)with their process and calculations. 2) Re-calculate the amount of vinegar needed to make a volcano using proper stoichiometry
For this question, you will review the student’s work below and identify the errors they made in their calculations.
A student wanted to make a huge volcano from vinegar and baking soda. If they used an entire box of baking soda (525 g), how much vinegar would they need? (most vinegar we buy at the store is 5%)
NaHCO3(s)+HCH3COO(aq)—>H2O(l)+NaCH3COO(aq)+CO2 (g)
They calculate the amount of vinegar using the following calculation. First, they decide to start with 1 mole of acetic acid and then multiply it by the mole ratio of 1:1 of acetic acid to baking soda. After that, they multiply by the grams of baking soda to end up with grams of acetic acid.
