Whats the options? I need to see some options before I answer please if there are any..
Answer:
-1.82 °C
Explanation:
Step 1: Given data
- Mass of NaCl (solute): 33.9 g
- Mass of water (solvent): 578 g = 0.578 kg
- Freezing point depression constant for water (Kb): -1.82 °C/m
Step 2: Calculate the molality of the solution
We will use the following expression.
m = mass of solute / molar mass of solute × kg of solvent
m = 33.9 g / 58.44 g/mol × 0.578 kg
m = 1.00 m
Step 3: Calculate the freezing point depression (ΔT)
The freezing point depression is a colligative property that, for a non-dissociated solute, can be calculated using the following expression:
ΔT = Kb × m
ΔT = -1.82 °C/m × 1.00 m
ΔT = -1.82 °C
Explanation:
Given parameters
Period = 2.34minutes
Unknown:
Frequency of the oscillator = ?
Solution:
Frequency is the number of waves that passes through a point at a given time. It is the inverse of period which is the time it takes for a wave to pass through a medium:
F = 
F is the frequency
T is the period
To solve this, convert the period to seconds:
2.34minutes to seconds:
1 min = 60seconds
2.34 = 60 x 2.34 = 140.4s
F = 
= 0.007hz or 0.007s⁻¹

Where's the list? It depends on which one it is. It could be Chlorine, silicon, or anything on the non metals side of the periodic table if you don't list it.
