Question

how many moles are in 54g of sliver
​

Answer 1

Answer:

0.50 mols Ag

Explanation:

Given the data, we have:

mass= 54g

molar mass of Silver (Ag): 107.8 g/mol

We want moles, we can convert grams > moles using the molar mass as a "bridge" between the 2.

$54g * \frac{1 mol}{107.8 g}= 0.50 mols Ag$

Keeping an eye on the units, we'll see 54g get cancelled out by 107.8 g/mol and we'll be left with moles of Silver.
