If some the hexane had evaporated from the stearic acid solution, what effect (if any) would it have on the experimental value o

f Avogadro’s number? Why?

Answer:

If some of the stearic-acid hexane solution had evaporated before using it, this would increase Avogadro's number, or the number of atoms per mole. This is because with less hexane in the solution (because only the hexane evaporates), the grams of stearic acid used would be smaller.

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.

What important ingredients do you need to create a fertilized egg
Darya [45]

Answer:

In the 1970s, Epel and other researchers showed that calcium is the essential factor that sparks development in eggs. As calcium levels rise, metabolic changes occur that cause the egg to divide and form into an embryo.
