"the factors that mainly affect in the formation of magma can be summarized into three: temperature, pressure, and composition"
I hope this helps =^._.^=
1/4 mol = 0.25 mol
6 months = 0.5 year
rate = 0,25 mol / 0.5 year = 0.5 mol/year or approx 0.042 mol/month
Rutherford's model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. ... It was after this that Rutherford began developing his model of the atom.
Answer:
The molecular weight is 
Explanation:
From the question we are told that
The mass of the sample is 
The temperature is 
The volume which the gas occupied is 
The pressure is 
Generally from the ideal gas equation we have that

Here n is the number of moles of the gas while the R is the gas constant with value 

=> 
=> 
Generally the molecular weight is mathematically represented as

=> 
=>
