If one iron nail weighs 2.0 grams, what would be the mass of 6.022 x 10^23 nails?
Maru [420]

Answer:

1.2x10^{24}g

Explanation:

Hello!

In this case, it is possible to treat this problem by using a proportional factor which indicates one iron nail equals 2.0 grams:

\frac{2.00g}{1nail}

Now, for an amount of 6.022x10²³ nails, the corresponding mass will be:

6.022x10^{23}nail*\frac{2.00g}{1nail} \\\\1.2x10^{24}g

Best regards!

How do you figure out how many valence electrons an element has?
Alik [6]
It's how many are in the element's outer layer. The layers go: 2, 8, then 8.

Ex-6 electrons. 1 layer is 2, the next layer has 4 left. If that layer holds 8, you can do 8-4 and it has 4 valence electrons.

Ex-10 electrons. 1 layer is 2, the next layer has 0 left. It has 8 valence electrons because the outermost layer is full with 8.

ex-11 electrons. 1 layer is 2, the next layer is full as well. 2+8=10; it has 1 left. So that element has only one valence electron.
