Question

question 2

1. how many moles are in 200 g of silver (ag)?

21,000 mol
0.54 mol
1.02 mol
1.05 mol

Explanation:

Step1: Find the molar mass of silver (Ag)

The molar mass of silver (Ag) is \( 107.87\ \text{g/mol}\).

Step2: Use the formula \( n=\frac{m}{M} \) (where \( n \) is the number of moles, \( m \) is the mass, and \( M \) is the molar mass)

Given \( m = 200\ \text{g} \) and \( M=107.87\ \text{g/mol}\), then \( n=\frac{200\ \text{g}}{107.87\ \text{g/mol}}\approx1.85\ \text{mol}\)

Answer:

1.85 mol
