Question

What is the mass of NaCl produced when 2.0 moles of chlorine gas

are reacted with excess sodium? The equation is given.
2 Na + Cl2 → 2 NaCl

Answer 1

Mass = 234 g

Step-by-step explanation:

Given data:

Mass of NaCl produced = ?

Moles of chlorine = 2.0 mol

Solution:

Chemical equation:

2Na + Cl₂ → 2NaCl

now we will compare the moles of NaCl with chlorine gas.

Cl₂ : NaCl

1 : 2

2.0 : 2/1×2.0 = 4.0 mol

Mass of NaCl;

Mass = number of moles × molar mass

Mass = 4.0 mol × 58.5 g/mol

Mass = 234 g
