1. How much NaCl can you get from 20g of NaOH?
NaOH + HCl →→ NaCl + H₂O


Sagot :

Answer:

29.25g

Explanation:

Number of moles = Mass / Molar mass

Number of moles of NaOH = 20g/(23 + 16 + 1)

= 0.5mol

1 mol of NaOH = 1 mol of NaCl

Therefore, 0.5mol of NaOH = 0.5mol of NaCl

0.5mol = Mass of NaCl / (23 + 35.5)

Mass = 0.5 × 58.5

= 29.25g

I hope this helps! ^^
