In carbon dioxide (CO2), how many grams of oxygen (O) would there be if there are 24 grams of carbon (C)?
Zarrin [17]

Answer:

64g of Oxygen

Explanation:

Firstly, carbon and oxygen react to form CO2 as follows;

C + O2 => CO2

According to the equation, one mole of C reacts with one mole of O2 to give one mole of CO2

Since molar mass of C= 12g/mol, O= 16g/mol

One mole of (C) contains 12g

One mole of O2 contains 16(2) = 32g

Hence, If there are 24g of C, there would be 24 × 32 / 12

= 768/12

= 64g

Hence, there would be 64g of oxygen if there are 24g of Carbon

Please help. What is the empirical formula mass for C4H12O4?
just olya [345]

61g/mol

Explanation:

The empirical formula of compound is its simplest formula. It shows the simplest ratio by which the atoms are combined.

  In the formula   C₄H₁₀O₄

 we have:

        4 moles of carbon     10 moles of hydrogen    4 moles of Oxygen;

                 4 : 10 : 4

The simplest ratio can be obtained by dividing through by the highest common factor which is 2;

              4/2   10/2    4/2

               2       5        2

the empirical formula is C₂H₅O₂

The formula mass is the sum of the atomic weights;

   C₂H₅O₂ = (2 x 12) + (5x1) + (2x 16) = 24 + 5 + 32 = 61g/mol

Every situation has several alternatives and every resource has several alternative uses as well. Thus, every decision comes with it an opportunity cost. <span>
