Number of moles of Cu in 63.546 g is 1 mole
1 / 63.546 = 0.0157366317
Number of moles in 1 g of Cu is 0.0157366317
0.0157366317 x 0.1431
0.002251912 moles will be the answer
Oceanic crust is more dense because it contains basalt which is more dense than granite which composes the continental crust.
Answer: equal
Explanation:
I believe the answer is equal but i would need more context.
The inputs of photosynthesis are light energy, and matter in the form of water absorbed through the roots, and carbon dioxide absorbed through the leaves.
Therefore an input of photosynthesis from the choices given is,
Sunlight
Answer:
The answer to your question is M = 36.49 g
Explanation:
Data
mass = 8.21 g
volume = 4.8064 L
Temperature = 200°C
Pressure = 1.816 atm
M = ?
Process
1.- Convert temperature to °K
°K = 273 + 200
°K = 473
2.- Calculate the number of moles
n = (PV)/RT
n = (1.816)(4.8064)/(0.082)(473)
n = 0.225
3.- Calculate the molar mass
M --------------- 1 mol
8.21 g ---------- 0.225 moles
M = (1 x 8.21)/0.225
M = 36.49 g
