First look at the molar mass of Al, which is 26.98 grams. That means that there are 26.98 grams in one mole of Al. To find the moles in your given sample of 64.1 grams, just divide that value by the molar mass of 26.98 grams. That will give you a final answer of 2.38 moles in 64.1 grams of Al.
Hope this helps!
The magnitude of these forces is directly proportional to boiling and melting points. In addition, molecular polarity<span> affects </span>solubility<span> in that polar molecules are best solvated by polar solvent molecules and nonpolar molecules are best solvated by nonpolar solvent molecules; i.e., "like dissolves like".</span>
I think the correct answer from the choices listed above is option 2. When the products of a reaction are hotter than the reactants the reaction is endothermic. The change in temperature is a measure of energy difference of the states. Since energy must be conserved, so there must be a source of energy for the system.
Answer: can u explain ur question please?
Explanation:
I think the correct answer from the choices listed above is option C. Lotions applied during winter season moisturize the skin very quickly. This is because the oils in the lotion enter the skin cells by means of facilitated diffusion. Hope this answers the question.
