Answer:
0.5 atm
Explanation:
Data obtained from the question include:
P1 (initial pressure) = 1 atm
V1 (initial volume) = 5L
V2 (final volume) = 10L
P2 (final pressure) =?
The gas is obeying Boyle's law since the temperature is constant.
Using the Boyle's law equation P1V1 = P2V2, the final pressure can be obtained as follow:
P1V1 = P2V2
1 x 5 = P2 x 10
Divide both side by 10
P2 = (1 x 5)/10
P2 = 0.5 atm
Therefore, the pressure is 0.5 atm
nothing will happen
if you calculate the water potiential for both solutions
you get 2(0.1)(R)(T) and 1(0.2)(R)(T)
which is the same thing, so its isotonic.
Explanation:
Given:
Number of atoms = 1.505 x 10²³
Let us solve for the number of moles and mass of this atom of sodium.
A mole of a substance is the amount of that substance that contains the avogadro's number of particles.
1 mole of Na = 6.02 x 10²³ atoms
Number of moles of Na = 
= 0.25moles
Mass of Na = number of moles x molar mass
Molar mass of Na = 23g/mole
Mass of Na = 0.25 x 23 = 5.75g

Explanation:
Electrons are floating around, and protons are outside of the nucleus center. The ones in the center are neutrons. I hope this helps.
