Question

Quizplus · Accepted Answer

To determine the number of moles of silver in 7.00 kg of silver, we need to use the molar mass of silver. The molar mass of silver is 107.87 g/mol.

First, we convert the mass of silver to grams:

7.00 kg x 1000 g/kg = 7000 g

Next, we use the molar mass to convert grams of silver to moles of silver:

7000 g / 107.87 g/mol = 64.9 mol

Therefore, there are 64.9 moles of silver in 7.00 kg of silver. Choice A is the correct answer.
