The conclusion that you can draw about the electron transitions that can take place for a magnesium atom is that the photons produced are not of a lone wavelength, therefore from many dissimilar levels to subsequent levels, with many different wavelengths joining to create white.

Calculate the number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7
aliina [53]

Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.

<u>Explanation:</u>

The properties and behavior of many solutions depend not only on the nature of the solute and solvent but also on the concentration of the solute in the solution. Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:

Molarity = \frac{moles-solute}{lites-solution},

Here , litres-solution = \frac{16.55}{1000} l = 0.01655l.

⇒ Molarity = \frac{moles-solute}{lites-solution}

⇒ 0.1475 = \frac{moles-solute}{0.01655}

⇒ moles-solute = 0.01655(0.1475)

⇒ moles-solute = 0.00244

Therefore, Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.

A compound contains 0.5 mol Na, 0.5 mol N, and 10 mol H. The empirical formula of the
lesya [120]

Answer:

NaNH₂₀

Explanation:

0.5 mol Na, 0.5 mol N, and 10 mol H

To obtain the empirical formulae, we find the mole ratio between the elements and this is done by dividing all through by the smallest mol (0.5)

Na = 0.5 / 0.5 = 1

N = 0.5 / 0.5 = 1

H = 10 / 0.5 = 20

The mole ratio is used to write the empirical formulae. It is given as;

NaNH₂₀
