Question

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

Answer 1

Given :

weight in gram = 7.3 g

volume in liter = 100 my = 0.1 L ( 1ml = 1/1000l )

molecular mass of HCL = 1+35.4 = 36.4 g/mol

concentration in g/ L = 73 g/ L

concentration in Mol / L = 2 Mol / L

thus, concentration in g / L is 73 g / L and concentration in Mol / L is 2 Mol / L
