<u>Answer:</u> The mass of sucrose required is 69.08 g
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
Or,
where,
= osmotic pressure of the solution = 8.80 atm
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of solute (sucrose) = ?
Molar mass of sucrose = 342.3 g/mol
Volume of solution = 564 mL (Density of water = 1 g/mL)
R = Gas constant = 
T = Temperature of the solution = 290 K
Putting values in above equation, we get:
Hence, the mass of sucrose required is 69.08 g
Answer:
they will expand
Explanation:
as they bring out they become red giants then eventually white dwarfs or the scarier options a black hole
N the nucleus, there are protons and neutrons. That's two parts.
<span>Outside the nucleus, there are electrons. That's a total of three parts and that is all that chemists discuss. Theoretical physicists talk about other sub nuclear "parts", but if you include them, the number goes way over 5. </span>
<span>The "shells", "sub-shells", "orbits", "orbitals", "probabilities" and the like are not physical parts, but only descriptions of energy</span>
The liquid which has a low boiling point and is a poor conductor of electricity is Methane (CH4).
<h3>What is covalent Compounds?</h3>
Covalent Compounds are compounds with low boiling point and are poor conductors of heat and electricity. Covalent compounds have strong intra-molecular bonds. This is because the atoms within the covalent molecules are very tightly held together.
Methane (CH4) is a liquid that has a low boiling point and is a poor conductor of electricity.
