Answer:
18.25g
Explanation:
First, we need to generate the equation for the reaction between hydrochloric(HCl) acid and sodium hydroxide(NaOH). The equation is given below :
HCl + NaOH —> NaCl + H2O
Next we determine the molar mass of HCl and NaOH as shown below
MM of HCI = 1 + 35.5 = 36.5g/mol
MM of NaOH = 23 + 16 + 1 = 40g/mol
From the equation,
36.5g of HCl reacted with 40g of NaOH.
Therefore, Xg of HCl will react with 20g of NaOH i.e
Xg of HCl = (36.5 x 20) / 40 = 18.25g
Therefore 18.25g of HCl will react with 20g NaOH
