Although units such as grams, kilograms and pounds (lb) are used in everyday life to measure the amount of substances, the unit “mole” (or mol) is common in chemistry–related fields. If 1 mol of silver weighs 108 g, how many kilograms of silver are there in a spoon made up of 3.09 mol of pure silver?

Question

Although units such as grams, kilograms and pounds (lb) are used in everyday life to measure the amount of substances, the unit “mole” (or mol) is common in chemistry–related fields. If 1 mol of silver weighs 108 g, how many kilograms of silver are there in a spoon made up of 3.09 mol of pure silver?

Answer 1

1 mole is 108 grams Ag so

3.09 moles must ber 3*108 = ? grams Ag.
Then Kg = grams/1000 = ?
By the way, so-called silver spoon aren't made of 100% Ag. Pure silver is too soft.

Answer 2

So it would be like 3(108)= 324

and then 324/1000= 0.324

Answer 3

To solve this problem, we need to convert the amount of silver given in moles to kilograms. Here are the steps to do that:

Step 1: Convert the given amount of silver in moles to grams using the molar mass.

The molar mass of silver is 108 g/mol (as given in the question).

So, for 3.09 mol of silver:
Mass in grams = 3.09 mol x 108 g/mol

Step 2: Convert the mass in grams to kilograms.

Since 1 kilogram (kg) is equal to 1000 grams (g), we can convert the mass in grams to kilograms by dividing by 1000.

Mass in kilograms = (3.09 mol x 108 g/mol) / 1000

Now, let's calculate the value:

Mass in kilograms = (3.09 mol x 108 g/mol) / 1000
Mass in kilograms = 334.12 g / 1000
Mass in kilograms = 0.33412 kg

Therefore, there are approximately 0.33412 kilograms of silver in a spoon made up of 3.09 mol of pure silver.
