<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We do as follows:
0.24 g (1 mol / 342.3 g) (
6.022 x 10^23 molecules / 1 mol ) =4.222 x 10^20 molecules

I think the best one is B
The correct answer is the last option among the choices given. The color that is bent the least by a prism is red. A white light is a collection of different colors where each color is associated with different wavelength and frequency. When this light is refracted through a lens or prism it splits into separate colors where red is the least bent by a prism.
Answer:
Chemical laws are those laws of nature relevant to chemistry. The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics shows that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry. Conservation of energy leads to the important concepts of equilibrium, thermodynamics, and kinetics.
