11.27 mol of carbon dioxide gas is equal to 252.45 L or 270.48 L
<h3>Further explanation</h3>
Given
11.27 mol of CO2
Required
Volume of gas
Solution
If the conditions are assumed to be at the STP state (Standard Temperature and Pressure) at T 0 ° C and P 1 atm, then Vm is 22.4 liters/mol.
so for 11.27 moles the total volume is:
11.27 mol x 22.4 L = 252.45 L
But if the conditions are assumed to be at RTP (Room Temperature and Pressure), Conditions at T 25 ° C and P 1 atm. Vm = 24 liters/mol, then the volume of CO2:
11.27 mol x 24 L = 270.48 L.
The sample contains both Fe and oxygen
The mass of the sample is 36 g
28 g are Fe and 8 g are O
So to find the percent composition we can calculate using the following formula
Percent composition of the element = mass of the element / mass of the sample x 100%
Percent composition of Fe = 28 g / 36 g x 100 % = 77.8%
Percent composition of O = 8 g / 36 g x 100 % = 22.2%
Answer:
The importance of crystal structure. The graphite-diamond mineral pair is an extreme example of the importance of crystal structure. These two very different minerals have exactly the same chemical formula (C), but the crystal structure of the two minerals is very different. In graphite, carbon atoms are bonded together along a flat plane, as shown in Figure 3.
