How many molecules are in 54.0 grams of CO2?

Chemistry
1 answer:
mote1985 [20]3 years ago
6 0

Answer:

7.38654 in 54 grams

Explanation:

To get moles, you divide grams of a substance by molecular weight. The molecular weight of CO2 is 44 g/mol. 54g divided by 44/mol  is 1.227moles.

You then need to multiply moles by Avogadro’s constant (6.022x10^23). That gives you 7.38654x10^23 molecules in 54 grams of CO2.

The stoichiometry of the reaction gives the molar ratio in which the reactants react with each other and the ratio in which products are formed.
The coefficients of the reactants in the reaction follow the stoichiometry 
the balanced chemical equation for the reaction is as follows;
2C₃H₆(g) + 9O₂(g)  ---> 6CO₂(g) + 6H₂O(l)

is there a relationship between the relative age of stars in the number/identity of element is found within them
lukranit [14]

Yes. Stars use fusion to create nuclear energy, which is what makes them "alive". The older they are, the "bigger" the element in them is. Hydrogen turns into Helium, and when hydrogen is used up, the helium starts fusing into bigger elements. it stops at iron however. Once stars start fusing silicon to iron, it is doomed because it takes more energy than it gives off.
