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:

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