N2O = 28 + 16 = 44g
number of moles
= given mass/molar mass
= 0.173/44
= 0.0039318
Amplitude is 5m and wavelength is 100m
!let me know if I'm wrong bc im a little rusty!

Through osmosis because the membrane is partially permeable, osmosis is
the movement of water molecules from a region of lower solute
concentration to a higher solute concentration.
is the answer

Answer:
a. 0.528 M ..
Explanation:
Hello!
In this case, since the given by-mass percent can be written as:

By using the density and molar mass of the solute, cadmium sulfate, we can compute the molarity, by also making sure we convert from mL to L of solution:

Thereby, the answer is a. 0.528 M .
Best regards.
Answer:
Density = 4.06 * 10^14
Explanation:
Givens
r = 1 * 10^-13 cm
m = 1.7 * 10^-24 grams
Formula
V = 4/3 * pi * r^3
D = m/V
Solution
Put the givens into the formula.
V = (4/3) 3.14 * (1 * 10^-13)^3 Find the value for r^3
V = (4/3) 3.14 * 1 * 10^-39 Find the volume. Indicate divide by 3
V = 1.256 10^-38/3
V = 4.1867 * 10^-39
Density = m / v
Density = 1.7*10^-24/4.1867*10^-39 Do the division
Density = .406 * 10^(-24 + 39)
Density = .406 * 10^15 grams/ cm^3
Answer: Density = 4.06 * 10^14
