The concentration of the solution is 5.0 molar, which is 5.0 mole/L. So in the 1.0 L of 5.0 molar KF salt solution, the moles of KF is 5.0molar*1.0L=5.0 mole. The molecular weight of KF is given in the question as 58.10 gram/mole, so the grams of KF is 58.10 gram/mole * 5.0 mole = 290.5 gram.
A) folded protein happens because this is the most stable conformation that has the most number of internal hydrogen bonds , which result in hydrophobic functional groups being on the outer sides of the protein and causing the hydrophobic effect
The volume increases and the final volume is 2.1 L
<h3>Why volume increases?</h3>
The volume of a gas is directly related to the heat and pressure. If temperature increases, volume increases.
If pressure increases, volume decreases
Based on Boyle's law,
The absolute temperature of a gas is directly proportional to the volume of the gas.
As the balloon change increases its temperature, the volume increases
The Boyle's equation is:
V₁T₂ = V₂T₁
Where,
- V is volume
- T is absolute temperature of 1, initial state and 2, final state of the gas.
Replacing :
V₁ = 2.0L
T₂ = 35°C + 273.15 = 308.15K
V₂ = ?
T₁ = 25°C + 273.15 = 298.15 K
2.0L x 308.15 K = V₂ x 298.15 K
2.1 L = V₂
Final volume is 2.1L
Hence, The volume increases and the final volume is 2.1 L
