Question

if x ml MHCL. is mixed with 20 ml 2M hcl a 2.5<MHCL the value of x is​

Answer 1

Answer:

Moles of HCl from

the first solution: (0.5*20)/1000 = 0.01

the second solution: (0.3*30)/1000 = 0.009

Hence, total number of moles = 0.01 + 0.009

= 0.019

And total volume of solution = 50 mL

Hence, concentration of the hybrid or mixed solution = 0.019 moles/(50/1000) Litre

=0.38M
