7. Given a 32.0 g sample of methane gas (CH), determine the pressure that would be exerted on a container with
pishuonlain [190]

Answer:

P = 58.52 atm

Explanation:

Given data:

Mass of sample = 32.0 g

Pressure of sample = ?

Volume of gas = 850 cm³

Temperature of gas = 30°C

Solution:

Number of moles of gas:

Number of moles = mass/molar mass

Number of moles = 32.0 g/ 16 g/mol

Number of moles = 2 mol

Pressure of gas:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

850 cm³ × 1L /1000 cm³ = 0.85 L

by putting values,

P× 0.85 L = 2 mol × 0.0821 atm.L/ mol.K  × 303 K

P = 49.75 atm.L/ 0.85 L

P = 58.52 atm

5. A standardized mass was known to weigh exactly 5.0000g. It was weighed on a newly
sergey [27]

Answer:

Absolute error = 0.001

% Error = 002 5

Explanation:

The absolute error is the the difference in the measured value and the actual value of a quantity.

Here the actual value is 5.0000 grams

The measured value is 5.001 grams

Absolute error

5.001 - 5.000\\= 0.001

Percent error

= \frac{AE}{AV}

Where AE stands for absolute error and AV stands for absolute value.

= \frac{0.001}{5.000} * 100\\

= 0.02 %
