Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
Cold you please repost the question
THIS IS A QUESTION REGARDING
ideal gas equation
which states that
PV = nRT
where;
P : Pressure (atm)
V : Volume (litres)
n : Number of moles of that gas(mol)
R : Real gas constant = 0.0821
T : Temperature of that gas(Kelvin)
hope this helps
Answer keys ? With out that I can't answer it Lol!!
