What mass in kilograms does 4.41 moles of copper have?

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

2b2t

explanation:

2b2t

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
