Question

The following reaction shows sodium carbonate reacting with calcium hydroxide.

Na2CO3 + Ca(OH)2 -> 2NaOH + CaCO3
How many grams of NaOH are produced from 20.0 grams of Na2CO3?
(Molar mass of Na = 22.989 g/mol, C = 12.01 g/mol, O = 15.999 g/mol, Ca = 40.078 g/mol, H = 1.008
g/mol) (5 points)

Answer 1

15.1

Step-by-step explanation:

Balance Equation: Na2CO3 + Ca(OH)2 = 2NaOH + CaCO3

Stoichiometry:

20gNa2CO3/1 x 1mNa2CO3/105.985gNa2CO3 x 2mNAOH/1mNA2CO3 x 39.996gNaOH/1mNaOH = 15.1 grams of NaOH

Answer 2

Its 15.1
