The molar mass of a substance M is defined as the mass (in grams) m per mole (n) of that substance. Place the mass in the numerator and the number of moles in the denominator and simplify
M=mn
=0.406g0.00105mol
=387gmol

The number of moles of cholesterol is n=0.00105mol
The mass of cholesterol is m=0.406g
Let us calculate the molar mass of cholesterol.
M=mn
=0.406g0.00105mol
=387gmol

This is easy if you use a ratio and watch dimensional analysis words

0.00105mol0.406gm=1moleXgms Now cross multiply to get:

0.00105molXgms=0.406gms1mole

Xgms=0.406gms0.00105mol×1

0.406gms0.00105mol=386.66gmsmol of cholesterol is what we want.

A pair of forces with equal magnitudes, opposite directions,and different lines of action is called a "couple". When acouple acts on a rigid object, the couple produces a torque thatdoes not depend on the location of the axis. The drawing shows acouple acting on a tire wrench, each force being perpendicular tothe wrench. Determine an expression for the torque produced by thecouple when the axis is perpendicular to the tired and passesthrough (a) point A, (b) point B, and (c) point C. Express youranswers in terms of the magnitude F of the force and the length Lof the wrench
