Correct answer
B0.01 M
Step-by-step explanation
Moles (n) =
0.001
Concentration (M) =
Given volume of urea is 100 ml = 0.1 litre
[Note : While calculating Concentration volume should always be in litre.]
0.01 M
0.001
Concentration (M) =
Given volume of urea is 100 ml = 0.1 litre
[Note : While calculating Concentration volume should always be in litre.]
0.01 M
