PLEASE HURRY AND SHOW WORK

IgorC [24]

Answer:

The answer to your question is P = 1.64 atm

Explanation:

Data

Volume = 2.5 x 10⁷ L

Temperature = 22°C

Pressure = ?

Moles = 1.7 x 10⁶

R = 0.082 atm L/ mol°K

Process

1.- Convert temperature to °K

Temperature = 22 + 273

= 295°K

2.- Use the Ideal gas law to solve this problem

PV = nRT

- Solve for P

P = nRT / V

- Substitution

P = (1.7 x 10⁶)(0.082)(295) / 2.5 x 10⁷

- Simplification

P = 41123000 / 2.5 x 10⁷

- Result

P = 1.64 atm

Silver was precipitated and collected by filtration. The experiment yielded .077g of silver after dying. The predicted yield was

PSYCHO15rus [73]

Answer:

Precentage error = 7.23%

Explanation:

The precentage error formula is the useful method for determining precision of your experimental result

It can be calculated using :

$percent\ error = |\frac{experimental\ value-predicted\ value} {predicted\ value}|\times 100$

$percent\ error = |\frac{0.077\ -0.083} {0.083}|\times 100$

So we get percentage error = 7.23%

Precision means how close the experimental value to the true value or theoretical value

If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment

If the percentage error is zero it means the experiment is perfectly done without inaccuracy
