Question

the molar mass is the conversion factor (1 mole li = 6.94 grams). what will go in the bottom of the fraction? 1 mole li 6.94 g rewatch

Explanation:

Step1: Recall molar - mass concept

Molar mass gives the mass of 1 mole of a substance. Here, for lithium (Li), 1 mole of Li has a mass of 6.94 g. The molar - mass conversion factor has moles in the denominator when converting from grams to moles. So, when using the conversion factor $\frac{1\ mol\ Li}{6.94\ g}$, the denominator is 6.94 g.

Answer:

6.94 g
