Answer: 2.4 M
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = 3.5 M
= volume of 
solution = 34.3 ml
= molarity of 
solution = ?
= volume of solution = 50 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of NaOH solution is 2.4 M.
The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.
Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.
So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.
X4O10
Let molar mass of X be y
molar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]
Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]
which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31
The answer to that is mass and chemical
Yes..? I don’t understand what you’re trying to ask mate.
