<span>One mole of a substance contains Avogadro's number of atoms/molecules/the like. This would mean that all of the items described would have approximately 6.022 * 10^23 atoms, even though their masses would differ. This would be due to the molar mass of each substance being different because of the constituent elements in the substance.</span>
The answer is na sodium, bromine
The Freezing point is ALWAYS the same as the melting point,even for different elements. 6,422 is its melting,and freezing point. Same with gold,iron,hydrogen,and many others
<span>the same
The formula for starch is C6H10O5 which has a ratio of 10 to 5 which reduces to 2 to 1 for the hydrogen to oxygen ratio. The formula for water is H2O which also has the ratio of 2 to 1 for hydrogen. Since the ratios are the same, the answer to the question is "the same". The name used for the category of nutrient that starch falls under should give a strong clue to the chemical formula. It's carbohydrate.</span>
