Why would scientists use molar volume to measure gases?

Chemistry
1 answer:
Serjik [45]2 years ago
5 0

Answer:

The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under <em>certain temperature and pressure conditions</em>.

scientists use molar volume to measure gas because it it tells us about volume occupied by gas.

<u><em>Molar volume</em></u>

  • The molar volume of a gas tell us about volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.
  • At STP(Standard Temperature and Pressure) condition which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.
  • The molar volume of a gas is derived from the ideal gas law <u><em>PV=NRT</em></u>

4300 m above sea level what is the boiling point
Olenka [21]
4300 meters = approximately 14107.61 feet. 

Boiling point is 212 degrees Fahrenheit at sea level.

(Each 500 feet increase in elevation will be lowered by approximately 1 degrees Fahrenheit)

14107.61 feet divided by 500 feet = <span>28.21522

So the boiling point would be lowered by about 28 degrees Fahrenheit at 4300 meters above sea level. Which will make your new boiling point 184 degrees Fahrenheit instead of 212. 

184 degrees Fahrenheit = 84.4 degrees Celcius</span>

For the reaction: h2nnh2 (aq) + h2o(l) ⇌ h2nnh3+(aq) + oh- (aq) determine the conjugate base of the acid?
never [62]
In this reaction, water acts as the base and donates a proton to hydrazine (H2NNH2). Hydrazine becomes protonated: [N2H5]<span>+ And thus hydrazine in this reaction is actually a base. The conjugate base of the acting acid H2O is OH- (hydroxide ion).</span>

Some gas molecules move at speeds of 542 meters per second. How fast is this in miles per hour? 542 =? 1h Solve by dimensional a
artcher [175]

Answer:

1212.42\ \text{mph}

Explanation:

We need to convert 542\ \text{m/s} to \text{miles/hour}

1\ \text{mile}=5280\ \text{ft}

1\ \text{ft}=12\ \text{inches}

5280\ \text{ft}=5280\times 12=63360\ \text{inches}

1\ \text{inch}=2.54\ \text{cm}=0.0254\ \text{m}

63360\ \text{inches}=63360\times 0.0254=1609.344\ \text{m}

So

1\ \text{mile}=1609.344\ \text{m}\\\Rightarrow 1\ \text{m}=\dfrac{1}{1609.34}\ \text{miles}

1\ \text{hour}=60\times 60\ \text{seconds}\\\Rightarrow 1\ \text{s}=\dfrac{1}{3600}\ \text{hour}

542\ \text{m/s}=\dfrac{\dfrac{542}{1609.34}}{\dfrac{1}{3600}}=1212.42\ \text{mph}

The speed of the gas molecules is 1212.42\ \text{mph}.
