Answer:
TRUE.
Explanation:
Hello,
In this case, since the fusion enthalpy of ice is +333.9 J/g and the fusion entropy is defined as:
We can compute it considering the temperature (0 °C) in kelvins:
Therefore answer is TRUE.

Answer:
The density of helgas sample is 17.8 g/cm³.
Explanation:
Given that,
Mass of sample of Rowena = 5 gram
Density = 8.9 g/cm³
Mass of sample of helga = 10 gram
We need to calculate the volume of sample
Using formula of volume
Where, m = mass
= density
Put the value into the formula
We need to calculate the density of helgas sample

Answer: 1.12 Liters
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mol of occupy = 22.4 L
Thus 0.05 mol of will occupy =
