The disrespect, you know that comments like that really hurt people. I hope you know hundreds of people will see this and you could really hurt someone just think of that. Have a nice day :)
Distribute the 5 to the (x-9), which leaves you with:
5x - 45 = 5x
Subtract 5x from both sides.
This leaves you with:
-45 = 0
which is false, meaning there is no solution to this problem.
The answer is A. No solution
Answer:
M = 184.1 g/mol
Explanation:
Given data:
Density = 5.95 g/L
Temperature = 100°C (100+273 = 373 K)
Pressure = 755 mmHg = (755/760 = 0.99 atm )
Molar mass of gas = ?
Formula:
d = PM/RT
Solution:
M = dRT / P
M = 5.95 g/L × 0.0821 atm.L/mol.K × 373 K/ 0.99 atm
M = 182.21atm.g/mol / 0.99 atm
M = 184.1 g/mol
A. Mg and S. Mg (Magnesium) and S (Sulfur) create MgS (Magnesium Sulfide).
