Question

write down the concentration of 7.3 gm HCI in 200 ml water in gm per liter and mole per liter. ​

Answer 1

ANSWER

7.3 g HCl in 100 mL solution :

Concentration of HCl in g L

−1

=

Volume of HCl in litre

Mass of solute in gram

=

100

7.3×1000

=73 gL

−1

In terms of gram per litre :

7.3 g of HCI in 100 mL has concentration = 73gL

−1

Molecular mass of HCI = 1 + 35.5 = 36.5

Molarity=

Volume of HCl in L

Mass of solute in moles

=

36.5×100

7.3×1000

=2mol L

−1

In terms of moles per litre:

7.3 g of HCl in 100 mL has concentration = 2mol L

−1
