The largest number of molecules is the same as the largest number of moles of this molecules
to calculate the number of moles you have to divide the mass by the molar mass
molar masses:
CO2: 44,01 g/mol
CH4: 16,04 g/mol
CBr4: 331,63 g/mol
CHBr3: 252,73 g/mol
largest nº of mol= 100/(the smallest molar mass possible)
= 100/16,04
=6,23 moles
all other molecules would be smaller than 6,23 moles because the molar mass is so high.
The answer is B : 1<span>00 g of ch4</span>
Answer:
Temperature
Explanation:
Temperature is the key factor in dividing the atmosphere into various layers.
"lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air)
Answer:
For H-Cl, the direction is towards the chlorine atom
For F-CH3, the direction is towards the flourine atom.
Explanation:
The dipole moment is a vector quantity. This implies that it has both magnitude and direction.
Thus, the direction of the dipole moment always points from the positive atom towards the negative atom.
This explains the fact that it points to chlorine in HCl and points to flourine in F-CH3
Calculate formula and then substitute values into the formula for mass.
V = lwh
= (3.12)(527)(220)
= 361732.8
M = Dv
= (721)(361731.8)
≈ 2608086.28 kg
I'm not exactly sure so :/
