Answer:
mass of carbon-dioxide = 0.262 g
Explanation:
Firstly, write the chemical equation of the reaction and balance the equation accordingly.
2NaHCO3(aq) → CO2(g) + H2O(l) + Na2CO3(aq)
Calculate the molecular mass of baking soda
molar mass of baking soda = 23 + 1 + 12 + 48 = 84 g
2 moles of baking soda = 2 × 84 = 168 g
molar mass of CO2 = 12 + 32 = 44 g
if 168 g of baking soda produces 44 g of carbon-dioxide
1 g of baking soda will produce ? grams of carbon-dioxide
cross multiply
mass of carbon-dioxide = 44/168
mass of carbon-dioxide = 0.2619047619
mass of carbon-dioxide = 0.262 g
