A sample of methane occupies a volume of 174.0 mL at 25 C and exerts a pressure of 1030.0 mmHg if the volume of the gas is allowed to expand to 650.0 mL at 298K what will be the pressure of the gas?

The pressure will be 0,37 atm.

Explanation:

We use the Boyle Mariotte´s formula,where for a given mass of gas, at constant temperature, the pressure and temperature vary inversely proportionally. We see here that the initial and final temperature does not vary (298K).

We convert the unit Celsius into Kelvin (0 ° C = 273K) and the unite mmHg into atm (760mmHg=1 atm):

25°C= 25+273=298K   ; (1060mmHgx 1 atm)/760mmHg)=1,39 atm.

We convert unit of volume from ml to L: 174/1000=0,174L and 650/1000=0,650L

P1xV1= P2xV2

1,39 atm x 0,174L =P2 x0,650L

P2= (1,39 atm x 0,174L)/0,650L= 0,37 atm

The pressure of the gas will decrease to 275.7 mmHg or 0.362 atm

Explanation:

Step 1: Data given

Volume of methane = 174.0 mL = 0.174 L

Temperature = 25.0 °C = 298 K

Pressure = 1030 mmHg = 1030/760 atm = 1.355263 atm

Volume increases to 650.0 mL = 0.650 L

The temperature stays constant

Step 2: Calculate the new pressure

P1*V1 = P2*V2

⇒with P1 = the initial pressure = 1.355263 atm

⇒with V1 = the initial volume = 0.174 L

⇒with P2 = the new pressure = TO BE DETERMINED

⇒with V2 = the new volume = 0.650 L

1.355263 * 0.174 = P2 * 0.650

P2 = 0.362 atm = 275.7 mmHg

OR

1030*0.174 = P2 * 0.650

P2 = 275.7 mmHg

The pressure of the gas will decrease to 275.7 mmHg or 0.362 atm

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'
