Question

How many mole of HCL is produced if 4g of hydrogen is completely reacted with chlorine​

Answer 1

Answer:

4 moles of HCl are produced.

Explanation:

Given data:

Mass of hydrogen = 4 g

Number of moles of HCl = ?

Solution:

H₂ +  Cl₂   →    2HCl

Number of moles of hydrogen:

Number of moles = mass/molar mass

Number of moles = 4 g/2 g/mol

Number of moles = 2 mol

now we will compare the moles of hydrogen and HCl.

                 H₂        :        HCl

                  1          :          2

                  2         :         2/1×2 = 4 mol

Thus, 4 moles of HCl are produced.
