Answer:
The weight-average molar mass of polystyrene is 134,160 g/mol.
Explanation:
Molar mass of the monomer styrene , , M=104 g/mol
Given , number average molar mass of the polymer , M'= 89,440 g/mol
Degree of polymerization = n
The weight-average molar mass =
Molar mass dispersity is ratio of weight-average molar mass to the number average molar mass of the polymer.
The weight-average molar mass of polystyrene is 134,160 g/mol.
Distance traveled by the race horse=6 furlongs
Converting the distance from furlongs to rods: 40 rods =1 furlong
Converting the distance from rods to yards, feet and miles: 5.5 yards = 1 rod, 3foot =1 yard, 1 mile = 5280 feet.
The given speed of race horse = 40.7mi/hr
Calculating the time required:
Therefore, 66.34 s is required for a race horse to run six furlongs at 40.7 miles per hour.
