Answer:
Explanation:
Ok, so I suppose you meant NaCl. But ok:
So we have the formula moles = grams/MM, where MM is molar mass. The molar mass of NaCl is 58.44 g/mol. That means that 55/58.44 is the number of moles which appears to be 0.94 moles.
Answer:
You can divide the mass by the volume to calculate the density of the metal
Explanation:
Answer:
In a solution the solvent is the liquid that the solute is added to.
Explanation:
Solute + Solvent = Solution.
For example: An aqueous solution of 10 g of NaCl in 100 g of water
NaCl → solute → what you dissolved
H₂O → solvent → where you dissolve
each isotope of a given element has a different mass number. For example, carbon-12, carbon-13<span> and carbon-</span>14<span> are </span>three<span> isotopes of the element carbon with mass numbers </span>12<span>, </span>13<span> and </span>14<span> </span>
Answer:
<h2>The electrons in beryllium and magnesium are too strongly bound to get excited by flame. Hence, these elements do not impart any color.</h2>
