Answer 2

730 grams of hydrogen chloride are required to prepare 4 Litre of 5M HCL in water

Given:

Molarity of HCl = 5M

Volume of HCl = 4liters

To find:

Grams of hydrogen chloride are required to prepare 4 Litre of 5M HCL in water

Solution:

We have a formula

Moles = Molarity × Volume

Thus,  

Moles of HCl = 5 × 4

                     = 20 moles

Now, the Atomic weight of HCl = 1+35.5

                                                    = 36.5

Now, Calculate the total grams of HCl

Total grams = Moles × Atomic weight

                    = 20 × 36.5

                    = 730 grams

Therefore, 730 grams of hydrogen chloride are required to prepare 4 Litre of 5M HCL in water
