Have you started doing the problem? What have you got so far?

2. Zale101

Hint: Yo have a conversion factor already been given to you. "There are 3.76 × 1022 atoms in 1 gram of oxygen. $$\LARGE\frac{3.76*10^{22} ~atoms}{1~gram~Oxygen}$$ or $$\LARGE\frac{1~gram~Oxygen}{3.76*10^{22} ~atoms}$$

its a simple multiplication $(3.76 \times 10^{22}) \times 700$ if your calculator is in scientific mode it should be able to handle this
