Question

calculate number of sulphate ions in 100 ml of 0.001 M H2SO4 solution.​

Answer 1

Answer:

6.023*10 to the power 19.

Explanation:

HCL= H+ Cl_

It is observed that one mole of HCL dissociates to give one mole of Cl_

M=(n*1000)/V

Therefore, n=(0.001*100)/1000=0.0001moles.

Since the number of moles of HCL=Number of CL_

Therefore, number of Cl_=

0.0001mole

1mole of CL_, contains 6.023*10 to the power 23 chloride ions

Now, 0.0001 mole of Cl_, will contain (6.023*10 to the power 23*0.0001)= 6.023*10 to the power 19 chloride ions.
