<span>The first thing a person has to do is determine how much volume of water ethyl alcohol contains. You do this by burning the liquid and the volume that sits at the bottom is water. You take this and then determine how much 3.0m3 has and that answer is 2.0ml.</span>

Escribe aquí algo que consideres que requiere un balance para que se lleve a cabo correctamente​
Solnce55 [7]

Answer:

Algo importante sobre el balance de una reacción química es la ley de la conservación de la masa que establece que la masa no se crea ni se destruye sólo se transforma de modo que en una reacción química la suma de la masa de los reactivos debe ser igual a la suma de la masa de los productos.

Por ejemplo: La fermentación de la glucosa es una reacción química balanceada que da como resultado etanol y dióxido de carbono.

C₆H₁₂O₆ → 2C₂H₆O +2CO₂

Calculando la masa de los reactivos y productos, se debe cumplir la ley de la conservación de la masa:

C₆H₁₂O₆= 6*12+12*1+6*16=180 g/mol

C₂H₆O= 2*12+6*1+16=46 g/mol

CO₂=12+2*16=44 g/mol

C₆H₁₂O₆ → 2C₂H₆O + 2CO₂

180 g/mol = 2*46 g/mol + 2*44 g/mol

180 g/mol = 92 g/mol + 88 g/mol

180 g/mol = 180 g/mol

At 741 torr and 44°C, 7.10 g of a gas occupy a volume of 5.40 L. What is the molar mass
amm1812

The molar mass of the gas is 35. glmol.

the molar mass of a chemical compound is described as the mass of a sample of that compound separated by the amount of substance in that sample, measured in moles.

The molar mass is a bulk, not molecular, effects of a substance.

<h3>What is molar mass and how is it calculated?</h3>

The molar mass is the mass of one mole of a sampling. To find the molar mass, count the atomic masses (atomic weights) of all of the atoms in the molecule. Find the atomic mass for each element by using the mass shown in the Periodic Table or table of atomic weights.

<h3>What is molar ?</h3>

Molar refers to the unit of concentration molarity, which is equivalent to the number of moles per liter of a solution. In chemistry, the word most often guides to molar concentration of a solute in a solution. Molar attention has the units mol/L or M.

To learn more about the molar mass, refer
