1. What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.30 m?
Sav [38]
Wave speed = frequency x wavelength 
                     =   100 x 0.3
                     =       30 m/s.

Hope this helps!

A chemist has a 2.0 M solution of copper (II) sulfate. Is he takes 400 mL of this solution and dilutes it with 1200 mL of water,
Ksenya-84 [330]

0.66 M is the accurate molarity of the new solution of volume of 1200 ml.

Explanation:

Data given:

molarity of copper(II) sulphate, Mconc.= 2M

volume of 2M solution taken Vconc. = 400 ml

volume taken for dilution, Vdilute = 1200 ml

molarity of the diluted solution, Mdilute =?

We will use the formula for dilution as

Mconc Vconc = Mdilute x V dilute  (conc is concentrated)

putting the values in the equation:

2 x 400 = Mdilute x 1200

Mdilute = \frac{800}{1200}

   Mdilute  = 0.66 M

When the solution is diluted to the volume of 1200 ml its molarity changes to 0.66 M.
