Answer:
n = 0.34 mol
Explanation:
Given data:
Given temperature = 789 K
Pressure = 765 torr ( 765/760 = 1.0 atm
Volume of container = 22.0 L
Number of moles of gas = ?
Solution:
Formula:
PV = nRT
n = PV/RT
n = 1.0 atm × 22.0 L / 0.0821 atm.L/mol.K ×789 K
n = 22.0 L.atm /64.8 atm.L/mol
n = 0.34 mol
Answer:
The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen.

The formula of compound is LiClO4.3H2O
<em><u>calculation</u></em>
- <em><u> </u></em>find the mole of each element
that is moles for Li,Cl,O and that of H2O
- moles = % composition/ molar mass
For Li = 4.330/ 6.94 g/mol= 0.624 moles
Cl=22.10/35.5=0.623 moles
39.89/16 g/mol =2.493 moles
H20= 33.69/18 g/mol= 1.872 moles
- find the mole ratio by dividing each moles by smallest number of mole ( 0.624 moles)
that is for Li= 0.624/0.623= 1
Cl= 0.623/0.623=1
O = 2.493/0.623 =4
H2O= 1.872/0.623=3
<h3>Therefore the formula=LiClO4.3H2O</h3><h3 />
