Question

What is the mass of carbon present in 44g of carbon dioxide.​

Answer 1

Answer:

12 g

Explanation:

Originally Answered: What is the mass of carbon present in 44g of carbon dioxide? 12 g of carbon is present in 44g of CO2. As 1 mole of CO2 contains 1 mole of C (as indicated by formula).

Answer 2

Answer:

$12g$ of carbon is present in $44g$ of carbon dioxide.

Explanation:

Mass of carbon dioxide $= 44g$

Molecular mass of carbon dioxide = Atomic Mass of carbon + 2 ( Atomic                     Mass of oxygen)

                                          $= 12 +2(16)$

                                          $= 12 +32$

                                            $= 44 g$

Number of moles of Carbon dioxide  $= \frac{Given- mass(CO_{2} )}{Molecular weight (CO_{2}) }$      

                                                              $= \frac{44}{44}$

                                                              $=1 mole$

$1 mole$ of $CO_{2}$ means $1 mole$ of carbon is present.

                                       $Moles(C) = \frac{Mass (C)}{Atomic-Mass(C)}$

                                                    $1 = \frac{Given-Mass}{12g}$

                                      $GivenMass = 12g*1$

                                                $Mass = 12g$

Therefore,$12g$ of mass of carbon is present in $44g$ of carbon dioxide.
