Which of the following steps correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine?

divide 6 by the atomic mass of fluorine.
divide the atomic mass of fluorine by 6.
subtract 6 from the atomic mass of fluorine.
multiply the atomic mass of fluorine by 6.

Divide 6 grams by the atomic mass of fluorine.

Explanation:

Number of moles = Mass / atomic mass of fluorine

Given data:

Mass of fluorine = 6 g

How to convert into moles of fluorine = ?

Solution:

Number of moles = Mass / atomic mass of fluorine

Number of moles = 6 g/  19 g/mol

Number of moles =  0.32 mol

So in order to convert the 6 g of fluorine into moles we have to divide the 6 by atomic mass of fluorine.

i can confirm that this is correct^

Explanation:

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
