Answer:
1.896 mol Cl
Explanation:
- Because the chloride is 67.2% chlorine by mass, i<u>n a 100 g sample of this compound, we would have 67.2 g of chlorine.</u>
With that information then we can calculate <u>the moles of chlorine</u> present in 67.2 g, using its atomic mass (accurate to 4 sig. fig. as the exercise asked):
67.2 g Cl ÷ 35.45 g/mol = 1.896 mol Cl
Yes what is it..we can help you
A neutral atom is one that has no net charge. In other words, the number of positive charges cancels out with the number of negative charges, so the number of protons equals the number of electrons. Uranium has 92 protons, which means it has a total positive charge of +92. To have a neutral charge, the atom MUST have 92 electrons, as that is a negative charge of -92, and the net charge is ultimately (protons + electrons) = ([+92] + [-92]) = 0.
The substances that dissolves in water are called solute.
