Answer:
107g
Explanation:
Magnesium fluoride (MgF₂) has a molecular mass of:
Mg: 24,305 g/mol × 1 = 24,305 g/mol
F: 18,998 g/mol × 2 = 37,996 g/mol
MgF₂ = 24,305g/mol + 37,996g/mol = 62,301g/mol. That means the mass of 1,72 mol of MgF₂ is:
1,72 mol F₂ × (62,301g / 1mol) = <em>107g</em>

When peroxide is swallowed, it generates oxygen bubbles in the stomach. Drinking higher concentrations of hydrogen peroxide can be very dangerous because it can cause tissue burns.
You must perform stoichiometry! always divide by what you already have (this will make since in a moment)
5.2g Carbon | 1 mole/12.01g/mole | 6.02 x 10^23 atoms/1 mole | = atoms in Carbon
above is the basic stoichiometry set up but your calculation should be (5.2g/12.01g) x (6.02 x 10^23) = 2.61 x 10^23 atoms
