Answer:

f = 1.09 × 10¹⁵ Hz

Explanation:

Given data:

Frequency of wave = ?

Wavelength of wave = 2.73 ×10⁻⁷ m

Solution:

Formula:

Speed of light = frequency × wavelength

speed of light = 3× 10⁸ m/s

by putting values,

3× 10⁸ m/s = f × 2.73 ×10⁻⁷ m

f = 3× 10⁸ m/s / 2.73 ×10⁻⁷ m

f = 1.09 × 10¹⁵s⁻¹

s⁻¹ = Hz

f = 1.09 × 10¹⁵ Hz

What is the concentration of a 1:10 dilution of a 2.5 M solution of NaCl? How would you prepare exactly 100 ml of such a solutio

Marina CMI [18]

<u>Answer:</u> The concentration of the solution is 0.25 M

<u>Explanation:</u>

Let the volume of solution of 2.5 M NaCl be 10 mL

We are given:

Dilution ratio = 1 : 10

So, the solution prepared will have a volume of = $\frac{10}{1}\times 1000=100mL$
