How many moles are present in 454 grams of co2?
a. 10.31 mol
b. 4.54 mol
c. 37.83 mol
d. 14.18 mol
e. 1.3 mol

The correct answer is Option A.

Explanation:

To calculate the number of moles, we use the formula given by the equation:

Where,

Given mass of = 454 grams

Molar mass of

Putting values in above equation, we get:

Hence, the correct answer is Option A.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
