Which equivalence factor should you use to convert from 38.2 grams of k to moles of k?
a
(38.2 g k/39.10 g k)
b
(38.2 g k/1 mol k)
c
(1 mol k/38.2 g k)
d
(1 mol k/39.10 g k)

(38.2 g K/39.10 g K)

Explanation:

To convert given masses into moles we use the formula :

Moles of K=

Given:

Mass of K= 38.2 grams

Molar mass of K=  39.10 g/mol

Putting in the values in the given formula, we get:

Moles of K=

Thus the moles are 0.98 moles.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
