Answer;

Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.

Explanation;

-Anaerobic respiration is a type of respiration that does not use oxygen. It is used when there is not enough oxygen for aerobic respiration.There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.

-The carbon dioxide produced as a by-product when yeast perform alcoholic fermentation on the sugar in the bread mix is the gas that causes dough to rise.  The sugars in produce like barley, grapes and other grains and fruits is what allows yeast to produce the bubbles and alcohol in beer, wine and other liquors.

If 0.896 g of a gas occupies a 250 mL flask at 20°C and 760 mm Hg of pressure, what is the molar mass of the gas?​
salantis [7]

Answer:

86.2 g/mol

Explanation:

Before you can find the molar mass, you first need to calculate the number of moles of the gas. To find this value, you need to use the Ideal Gas Law:

PV = nRT

In this equation,

-----> P = pressure (mmHg)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas constant (62.36 L*mmHg/mol*K)

-----> T = temperature (K)

After you convert the volume from mL to L and the temperature from Celsius to Kelvin, you can use the equation to find the moles.

P = 760 mmHg                                      R = 62.36 L*mmHg/mol*K

V = 250 mL / 1,000 = 0.250 L              T = 20 °C + 273.15 = 293.15 K

n = ? moles

PV = nRT

(760 mmHg)(0.250 L) = n(62.36 L*mmHg/mol*K)(293.15 K)

190 = n(18280.834)

0.0104 = n

The molar mass represents the mass (g) of the gas per every 1 mole. Since you have been given a mass and mole value, you can set up a proportion to determine the molar mass.

\frac{?grams}{1 mole} =\frac{0.896grams}{0.0104moles}                                      <----- Proportion

?grams(0.0104moles) = 0.896                       <----- Cross-multiply

?grams = 86.2                                               <----- Divide both sides by 0.0104

A cubic object has a volume of 250 cm. What is its density if its mass is 5 points<br> 257.3 g?
ira [324]

Answer:

<h3>The answer is 1.03 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 257.3 g

volume = 250 cm³

We have

density =  \frac{257.3}{250}  \\  = 1.0292

We have the final answer as

<h3>1.03 g/cm³</h3>

Hope this helps you
