Answer:
Avogadro's Number
Explanation:
6.02 x 10²³ is the number of units it 1 mole.
6.02 x 10 ²³ is known as Avogadro's number
Answer:
We, apply equal torque to both spheres and measure their final angular acceleration.
Explanation:
The moment of Inertia of solid sphere will be (2/5)mr²
The moment of Inertia of hollow sphere will be (2/3)mr²
Thus, the moment of inertia of inertia of hollow sphere is greater than that of the solid sphere. Since, the torque is equal to the product of moment of inertia and angular acceleration.
Therefore, we design a test such that we apply the same amount of torque to both the spheres. Due to greater amount of moment of inertia the hollow sphere will acquire high angular acceleration, while solid sphere will acquire low angular acceleration.
Hence, by the measurement of final angular acceleration, we can determine, which sphere is which.

Volume of a rectangle:
L x W x H
12.49 x 4 x 0.90 = 44.964
Answer:
A solution exhibits colligative properties since solute interferes with the interaction of the atoms which would change certain properties of the solution. It's the freezing point that is affected. Here's how we solve it:
ΔT = kf (m) i
where kf is the freezing point depression constant which is 1.86 for water
m= molality
i= the van't hoff factor which is 2 for NaCl
ΔT = 1.86(0.321) 2
ΔT = 1.19412 °C
1.19412 °C = 0 - T
T = -1.19412 °C
Round your answer with 3 decimal places, which is -1.194°C
Hope this helps and stay safe during these crucial we will get through this!
