A balloon filled with helium gas occupies 2.50 L at 25°C and 1.00 atm. When released, it rises to an altitude where the temperat
stira [4]

Answer:

8,19 L

Explanation:

The combined gas law is a equation that can be used <em>when the initial and final conditions -</em>pressure,volume,amount of moles,temperature-, <em>of a gas change</em> during a process. It can be written:

\frac{P1V1}{n1T1}=\frac{P2V2}{n2T2}

If the amount of the gas remains constant, then n1=n2 and we have:

\frac{P1V1}{T1}=\frac{P2V2}{T2}

For the problem we have:

<em>Note: When working with gases is important to use </em><em><u>absolute temperature values (°K, °K=°C+273,15):</u></em>

P1=1 atm, V1=2,5L, T1=25+273,15=298,15°K

P2=0,3 atm, V2=?, T2=20+273,15=293,15°K

V2=\frac{P1V1T2}{T1P2}=\frac{1atm*2,5L*293,15K}{298,15K*0,3atm}=8,19L

The new volume of the balloon is 8,19 L.

If the molar mass of NaCl is 58.44 g/mol, what amount of NaCl (in mol) is contained in 250.0 mg of NaCl?
4vir4ik [10]

Answer: 0.004 moles

Explanation:

Amount of substance= mass/ molar mass

Mass= 250mg or 0.25g

Molar mass= 58.44gmol-1

Amount= 0.25/58.44

= 0.004 moles

Landslides and slumps are forms of mass movements. Types of erosion both move, in different ways. In slumps, land breaks off in one piece, or chunk. Landslides are when rocks and dirt rapidly move down a slide.
