Chemistry
1 answer:
Levart [38]3 years ago
5 0

Answer:

1,239,284pa

Explanation:

Assuming it's an ideal gas we use

PV=nRT

P=nRT/V

then we convert our Temperature into Kelvin

T=25+273.15 =298.12K

we convert our volume into M cubed

1.5L =0.0015 cubic meter

P=nRT/V

P= (0.75×298.12×8.314)/0.0015

P = 1,239,284pa

A gas occupies a volume of 584 mL at a pressure of 770 mm of Hg. When the pressure is changed, the volume becomes 603 mL If the
Blizzard [7]

Answer:

P_2=795mmHg

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the final pressure by using the Boyle's law as an inversely proportional relationship in pressure to volume at constant temperature:

\frac{P_2}{V_2} =\frac{P_1}{V_1}

Thus, we solve for our target, P2, to obtain:

P_2=\frac{P_1V_2}{V_1} =\frac{770mmHg*603mL}{584mL}\\\\P_2=795mmHg

Regards!

At STP, which 2.0-gram sample of matter uniformly fills a 340-milliliter closed container?
Xelga [282]

Answer;

D, Xe (g)

Solution and explanation;

If 2g has a volume of 340ml.

Density is 1000/340*2 = 5.88g/litre.

-This rules out the two solids, choices 2) &3)

If 1 litre has mass 5.88g,

then 22.4 liters (volume at STP) has mass 5.88*22.4 = 131.8g/mol

molar mass Br2 = 80*2 = 160g/mol NO

molar mass Xe = 131.3g/mol = YES.

Answer is Xe
