Question

Using the equation below to helpNa2CO3(s) + 2HCl(aq) --> 2NaCl(aq) + CO2(g) + H2O(1)What mass of sodium chloride can be produced from 27.2 g of sodium carbonate

Answer 1

We write the chemical equation:

$Na_2CO_3+2HCl\to2NaCl+CO_2+H_2O,$

And we have 27.2 g of Na2CO3 (sodium carbonate), so we calculate the atomic mass::
