In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.

Answer:
68.81ml
Explanation:
Using the formula:
CaVa = CbVb
Where;
Ca = concentration of acid (M)
Cb = concentration of base (M)
Va = volume of acid (ml)
Vb = volume of base (ml)
Based on the information given in this question;
Ca = 0.545M
Cb = 0.150M
Va = 250ml
Vb = ?
Using CaVa = CbVb
0.545/250 = 0.150/Vb
Cross multiply
250 × 0.150 = 0.545Vb
37.5 = 0.545Vb
Vb = 37.5/0.545
Vb = 68.81ml
