Question

If you eat 3.00 moles of sugar, how many molecules did you consume?

Answer 1

Answer:

$Molecules\ sugar=1.81x10^{24}molecules\ sugar$

Explanation:

Hello,

In this case, Avogadro's number help us to realize that 1 mole of any substance has 6.022x10²³ molecules of the same substance, in such way, by applying that relationship one computed the consumed molecules of sugar as shown below:

$Molecules\ sugar=3.00mol\ sugar*\frac{6.022x10^{23}molecules\ sugar}{1mol\ sugar} \\Molecules\ sugar=1.81x10^{24}molecules\ sugar$

Best regards.

Answer 2

According to Avogadro's law 1 mole of a substance contains 6.022×10^23 particles.
Thus, 1 mole of sugar contains 6.022×10^23 molecules 
Hence, 3 moles of sugars will contains;
 = 3 ×6.022 ×10^23 molecules
= 18.066 ×10^23 molecules
≈ 18.1 ×10^23 molecules
