Construct a perpendicular bisector for a line segment of measure 9 cm.6. Construct a perpendicular bisector for a line segment of measure 9 cm.

Answer 2

The total formula weight of the organic matter in the solution is 258 g/mol

GIVEN:- i) Glucose = 200 mg/l and ii) Benzene = 25mg/l

TO FIND:- formula weight of the organic matter in the solution

SOLUTION:-

• The formula weight of the organic matter in the solution can be determined by summing the respective weights of the two components. So, The formula weight of the organic matter in the solution can be calculated by adding the individual formula weights of glucose and benzene together.

For glucose, the molecular weight is 180.16g/mol and for benzene, the molecular weight is 78.11g/mol.

For calculation let the formula weight of glucose be 180 g/mol and the formula weight of benzene be 78 g/mol.

Accordingly, the total formula weight of the organic matter in the solution = 180 + 78 = 258 g/mol.

Hence, the total formula weight of the organic matter in the solution is 258 g/mol
