The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount. There for the answer is 33.1% or 3.3g/kg
Answer:
Amplitude does not effect the wavelength in linear system.
Explanation:
Amplitude:
It is the measure of height from peak to trough.
Wavelength:
It is measure of length from peak to peak.
There is no relation between the amplitude and wavelength but if the system will no more linear then high amplitude can cause the distortion in wave if more frequencies are present. However frequency and wavelength can be related. The wave with higher frequency have shorter wavelength and vise versa.
Frequency:
It is the number of waves passing through a given point in a given time period. It is measure in Hz or s⁻¹
<u>Answer:</u> The density of NaCl solution is 3.930 g/mL
<u>Explanation:</u>
We are given:
Mass of cylinder,
= 21.577 g
Mass of NaCl and cylinder combined, M = 39.664 g
Mass of NaCl,
= 
To calculate density of a substance, we use the equation:

We are given:
Mass of NaCl = 18.087 g
Volume of NaCl solution = 4.602 mL
Putting values in above equation, we get:

Hence, the density of NaCl solution is 3.930 g/mL
Answer:
a
. eight tenths of her cookies
Explanation:
Let the total number of Lakesha's cookies be represented by x.
So that;
She gave three tenths to Bailey =
of x
= 
She gave five tenths to Helen =
of x
= 
Fraction of Lakesha's cookies given away =
+ 
= 
= 
Thus, the fraction of cookies given away by Lakesha is
.
The correct answer is C. Colligative properties only depend upon the number of solute particles in a solution but not on the identity or nature of the solute and solvent particles. I hope this anwers your question.
