How many moles are in 12.3 grams of co2

The amount of carbon dioxide for a given amount are 0.28 moles.

Explanation:

To calculate the number of moles, we use the equation:

We are given:

Given mass of carbon dioxide = 12.3 g

Molar mass of carbon dioxide = 44 g/mol

Putting values in above equation, we get:

Hence, the amount of carbon dioxide for a given amount are 0.28 moles.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
