I think it will be B. Hope it helps :)
The pressure of the nitrogen gas produced is determined as 44.77 atm.
<h3>
What is the pressure of the Nitrogen gas?</h3>
The pressure of the nitrogen gas is determined from ideal gas equation, as shown below;
PV = nRT
P = nRT/V
where;
- n is number of moles = 2 moles
- R is ideal gas constant = 0.08205 L.atm/mol.K
- T is temperature = 68⁰C = 68 + 273 = 341 K
- V is volume = 1.25 L
P = (2 x 0.08205 x 341)/(1.25)
P = 44.77 atm.

Hi! To find the amount of grams in 2.34 moles of cobalt, you must use the following equation:
2.34 mol Co * (58.93 g Co)/(1 mol Co)
The answer would therefore be 137.9 grams
Answer:
<h3>The answer is 1.12 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 8.96 g/mL
error = 8.96 - 8.86 = 0.1
We have
We have the final answer as
<h3>1.12 %</h3>
Hope this helps you
