Answer:
The molar mass is determined by applying the Ideal Gas Law, PV = nRT, where P is the pressure (in atm), V is the volume (in L), n is the number of moles of gas, R is the universal gas constant (0.08206 L∙atm/mol∙K), and T is the temperature (in K).

Answer: 1.5 x 10^24
Explanation: Just multiply 2.5 by avagadro's number 6.2 x 10^23 to get the answer.
The answers would be the mass before a reaction is the same as the mass after a reaction which basically means mass is conserved
Answer: 35.4 g
Explanation:
The balanced reaction is :
To calculate the moles :
According to stoichiometry :
2 moles of phosphorous chloride are produced by = 3 moles of 
Thus 0.37 moles of phosphorous chloride are produced by=
of
Mass of 
Thus 35.4 g of chlorine reacted with the phosphorus
Answer:
<h2>1.806 × 10²⁴</h2>
Explanation:
The number of molecules can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 3 × 6.02 × 10²³
We have the final answer as
<h3>1.806 × 10²⁴</h3>
Hope this helps you
