<em>That contains 200g of sodium nitrate. Round to 2 significant digits</em>
To solve this question we need to convert the mass of NaNO3 to moles using its molar mass (85g/mol). With the moles and the molar concentration we can find the volume in liters of the solution:
because the more times that the waves pass a certain distance in a certain time the smaller the wave will be. so the more waves that fit in it the shorter the wavelength.
