aalyn [17]3 years ago
5 0

Answer:

0.280 kg

Explanation:

m= n × MM

where

m is mass in grams

n is moles &

MM is molecular mass

The molecular mass of copper can be found on the periodic table and is 63.546.

We now have all the required information to perform the calculation

m= 4.41 × 63.546

m= 280.23786

m= 280 g

In order to convert this value to kilograms, divide by 1000

280/ 1000

= 0.280 kg
