Best Answer: According to that chemical formula, there are 2 moles of Carbon for every molecule of CH3CH2OH. One mole of Carbon is 12.01 grams. You also have 6 moles of Hydrogen at 1.008 grams per mole and 1 mole of Oxygen at 16.0 grams per mole.ou need to find the number of moles of the compound that you have. The molar mass of ethanol is 46, so you have approximately 0.1 moles of ethanol. Given that there are 2 carbons in the formula, it's roughly 0.2 moles of carbon atoms. TheOnlyBeldin Â· 9 years ago.
The SI unit of solid angle measurement is the steradian. The radian is represented by the symbol rad or, more rarely, by the superscript c. For example, an angle of 1.2 radians would be written as 1.2 rad or 1.2c.
What is the point of using radians for measuring angles? Why not simply stick with degrees? One can answer all the questions perfectly well by converting the radians into degrees, working out the answer, and converting back into radians at the end if necessary. So why bother with radians in the first place?Let us first remind ourselves of the definition of a radian: In a circle with centre O and radius r, if points P and Q on the circumference of the circle are such that angle POQ is one radian, then the length of the arc PQ is equal to the radius of the circle.hat is the point of using radians for measuring angles?
