A drip bag holds 90.08 g of glucose, C₆H₁₂O₆, of molar mass 180.16 g mol⁻¹.

Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

A drip bag holds $90.08$ g of glucose, $\text{C}_6\text{H}_{12}\text{O}_6$ , of molar mass $180.16\ \text{g mol}^{-1}$ . How many moles of glucose is this? How many molecules? And how many atoms in all?

Need a reminder? The key ideaShow

One mole is $6.022 \times 10^{23}$ particles, the Avogadro constant $N_A$ . The molar mass $M$ in g/mol has the same number as the molecular mass in u. The amount is $n = \dfrac{m}{M}$ , and the number of particles is $N = n \times N_A$ .

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
