Fermentation is a complex chemical process of wine making in which glucose is converted into ethanol and carbon dioxide: C6H12O6

attashe74 [19]

Answer:

Mass of ethanol obtained is 260.682 grams.

Volume of the ethanol obtained is 0.3304 L.

Explanation:

$C_6H_{12}O_6\rightarrow 2C_2H_5OH + 2CO_2$

Moles of glucose = $\frac{510.6 g}{180 g/mol}=2.833 mol$

According to the reaction, 1 mol of gluocse gives 2 moles of ethanol.

Then 2.833 moles of glucose will give :

$\frac{2}{1}\times 2.8333 mol=5.667 mol$

Mass of 5.667 moles of an ethanol :

5.667 mol × 46 g/mol = 260.682 g

Volume of ethanol = V

Density of the ethanol = 0.789 g/mL

$Density=\frac{Mass}{Volume}$

$0.789 g/mL=\frac{260.682 g}{V}$

$V=\frac{260.682 g}{0.789 g/mL}=330.40 mL = 0.3304 L$

Mass of ethanol obtained is 260.682 grams.

Volume of the ethanol obtained is 0.3304 L.

How many moles is 2. 2 grams of CO2?.

lorasvet [3.4K]

The number of moles of carbon dioxide is 0.05 mol.

A molecule of CO2 contains one carbon atom and two oxygen atoms. One mole of CO2 contains one mole of carbon atoms and two moles of oxygen atoms. The mass of one atomic mole of an element equals the atomic mass in grams, and the molecular mass of an element or compound equals the sum of the atomic masses of each type of its constituent atoms.

Therefore, the mass of one mole of a molecule of an element or compound equals its molecular weight in grams. The number of grams in moles depends on the substance you have. To calculate it, find the atomic or molecular mass of the substance and multiply it by the number of moles.
