M(dextrose) = 50 g.
V(solution) = 1 L.
n(dextrose) = 50 g ÷ 180 g/mol.
n(dextrose) = 0,27 mol.
Osmotic concentration (osmolarity)<span> is a measure of how many </span><span>osmoles of particles of solute</span><span> it contains </span>per liter.
The osmolarity = n(dextrose) ÷ V(solution).
The osmolarity = 0,27 mol ÷ 1 L.
The osmolarity = 0,27 mol/L · 1000 mmol/m.
The osmolarity (dextrose) = 270 mosm/L.
The osmolarity (dextrose monohydrate) = 50 g÷197 g/mol·1000 =254mosm/L
Ow many grams of NH3 can be produced from the reaction of 28g of N2 and 25g
Friction. Imagine rubbing your hand against a carpet and how it gets hot even though you are pushing it afar. That is friction.
Answer:
The system is not at equilibrium and the reaction will shift to the right until Kp = Q
Explanation:
For the reaction:
cis-2-butene ⇌ trans-2-butene
Kp is defined as:
<em>Where P is the pressure of each gas in equilibrium.</em>
If initially, a flask contains 5.00atm of each gas, Q of reaction will be:
Q = 5.00 atm / 5.00 atm = 1.
As Kp > Q, <em>the system is not at equilibrium and the reaction will shift to the right until Kp = Q</em>
