Started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
The organelle is the chloroplast. While plant cells will also have a cell wall, the cell wall is not considered an organelle.
Answer:
0.02 mol
Explanation:
Given data:
Number of moles of nitrogen = ?
Volume of sample = 400 cm³
Pressure = 790 mmHg
Temperature = 27°C
Solution:
Volume of sample = 400 cm³ (400/1000=0.4 L)
Pressure = 790 mmHg (790/760 = 1.04 atm)
Temperature = 27°C (27+273=300 K)
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1.04 atm ×0.4 L = n× 0.0821 atm.L/ mol.K ×300 K
0.416 atm.L = n× 24.63 atm.L/ mol
n = 0.416 atm.L /24.63 atm.L/ mol
n = 0.02 mol
