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.
