Answer:
I > III > II
Explanation:
The osmotic pressure (π) is a colligative property that can be calculated using the following expression.
π = M × R × T
where,
M is the molarity of the solution
R is the ideal gas constant
T is the absolute temperature
As we can see, there is a direct proportionality between the molarity of the solution and its osmotic pressure. As a consequence, the correct order for osmotic pressures is:
I > III > II
In meiosis there are haploid cells because two cells are being combined to make one, while in mitosis there are diploid cells because they are splitting apart.
Answer:
The answer is 4
Explanation:
You divide the grams by the volume which will give you the density
so 19.2 divided by 4.8 equals 4
The amount of heat required is 9.0 kJ.
<em>q = mC</em>Δ<em>T
</em>
Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = 65 °C – 32 °C = 33 °C
<em>q</em> = 65 g × 4.184 J·°C⁻¹g⁻¹ × 33 °C = 9000 J = 9.0 kJ
