commercial HCL IS SOLD AT 37% WITH SPECIFIC GRAVITY OF 1.18.HOW WILL YOU PREPARE 5OML FOR 100STUDENTS AT THE CONCENTRATION OF 0.25M

Answer 1

First, calculate the molarity of the concentrated solution of HCl.
1.18 g/mL x 1000 mL x 0.37 x (1/36.5) = approximately 12 M. Then
mL1 x M1 = mL2 x M2
mL x 12 = 5000 x 0.25
