Answer: 149
Explanation:
Using the ideal gas equation; PV = nRT
P= Pressure = 0.910 atm, T= Temperature = ?
V= Volume = 4.0L R = Gas constant = 0.08206 L.atm/mol/K
n = number of moles = 0.297
Making 'T' the subject of the formular, we have;
T = P V/ n R = 0.910 x 4 / 0.297 x 0.08206
= 149

Explanation:
Conduction:
Transfer of heat due to direct contact between two mediums at different temperatures, without having any of the bodies traveling. Therefore, conduction heat transfer occurs by the transfer of momentum (molecular) from always the same group of molecules in one medium to another group of molecules in another medium.
Example: Heat transfer INSIDE a solid.
Convention:
Transfer of heat or mass due to at least one traveling medium, where the transfer of momentum is not bounded anymore to the same groups of molecules. Molecules moving to transfer their momentum and keep flowing to the next group, also allowing other molecules behind to do the same. Example: heat transfer by the wind.
Hence, the Mass transfer rate in convection is <u>more than</u> mass transfer in conduction

Answer:
SiBr₄= 347.7 g/mol
Explanation:
Gram formula mass:
Gram formula mass is the atomic mass of one mole of any substance.
It can be calculated by adding the mass of each atoms present in substance.
SiBr₄:
Atomic mass of Si = 28.1 amu
Atomic mas of Br = 79.9 amu
There are four atoms of Br = 79.9 ×4
There is one atom of Si = 28.1 × 1
Gram formula mass of SiBr₄:
SiBr₄ = 79.9 ×4 + 28.1 × 1
SiBr₄= 319.6 + 28.1
SiBr₄= 347.7 g/mol
