Question

Does anyone know the answer to this chemistry question?!?

How much HCl is made when 2g of hydrogen reacts?

H2+Cl2->2HCl

Answer 1

Answer:

Mass of HCl = 73 g

Explanation:

Given data:

Mass of hydrogen = 2 g

Mass of HCl = ?

Solution:

First of all we will write the balance chemical equation:

H₂ + Cl₂   →  2HCl

Number of moles of hydrogen = 2 g/ 2g/mol

Number of moles of hydrogen = 1 mol

Form balanced chemical equation compare the moles hydrogen with HCl.

                   H₂    :   HCl

                    1      :    2

Mass of HCl:

Mass of HCl = number of moles × molar mass

Mass of HCl = 2 mol × 36.5 g/mol

Mass of HCl = 73 g
