Baking soda (sodium bicarbonate) is a compound commonly used in baked goods, as a deodorizer in refrigerators, and as an antacid. Commercial quantities of baking soda are produced by mixing soda ash dissolved in water with carbon dioxide. Baking soda precipitates as a solid from this method:
Na2CO3 + CO2 + H2O → 2NaHCO3
How many grams of soda ash would be needed to produce 1,000 g of sodium bicarbonate?

Sagot :

Answer:631 g

Explanation: bc i did the math

630.581 grams of soda ash would be needed to produce 1,000 g of sodium bicarbonate.

How we calculate moles from grams?

Moles can be related to the mass or weight of any substance as follow:

n = W/M, where

W = given mass

M = molar mass

Given balanced chemical equation for the formation of sodium bicarbonate is:

Na₂CO₃ + CO₂ + H₂O → 2NaHCO₃

From the stoichiometry of the reaction, it is clear that:

1 mole of Na₂CO₃ is required = to form 2 moles of NaHCO₃

Or 1/2 mole of Na₂CO₃ is required = to form 1 moles of NaHCO₃

Moles of NaHCO₃ be calculated by using the above formula as:

n = 1,000g (given) / 84.007g/mole = 11.90 moles

So, moles of Na₂CO₃ required to form 11.90 moles of NaHCO₃ = 11.90×1/2 = 5.95 moles

Now we convert the mole of Na₂CO₃ to grams by using the mole formula:

W = 5.95mole × 105.98g/mole = 630.581 grams.

Hence, 630.581 grams of soda ash would be needed.
