What is the osmotic pressure of a .25 M solution of NaCl at 25 degrees Celsius?
Ilya [14]

Answer:

6.113 atm

Explanation:

Data provided in the question:

Molarity of the solution = 0.25 M

Temperature, T = 25° C = 25 + 273 = 298 K

Now,

Osmotic pressure (π) is given as:

π = MRT

where,

M is the molarity of the solution

R is the ideal gas constant = 0.082057 L atm mol⁻¹K⁻¹

on substituting the respective values, we get

π = 0.25 × 0.082057 × 298

or

π = 6.113 atm

What is the concentration of a solution formed when 4.00 grams of sodium hydroxide is dissolved to make 250cm cubed of solution
morpeh [17]

0.4M is the concentration of a solution formed when 4.00 grams of sodium hydroxide is dissolved to make a 250cm cubed solution.

Molar concentration, also known as molarity, quantity concentration, or substance concentration. Molarity is a unit used to describe the amount of a substance in a solution expressed as a percentage of its volume. The number of moles per liter, denoted by the unit symbol mol/L or mol/dm³ in SI units, is the most often used unit denoting molarity. Because the volume of most solutions very minimally changes with temperature owing to thermal expansion, using molar concentration in thermodynamics is frequently not practical.

The formula for molarity,

Molarity = (moles/vol) x 1000

             = \frac{4/40}{250} x 1000

​              = (0.1 / 250) x 1000

             =0.4M

What is the mass number of an alpha particle?<br> (1) 1 (3) 0<br> (2) 2 (4) 4
Lesechka [4]
Your answer is (4) 4, because the alpha particle is a helium nucleus (either an ion or an ejected particle from alpha decay), and it has a mass number of 4, being consisted of four nucleons, (2 protons and 2 neutrons).
