Explanation
The conversion factor we will need is [tex]oz * \frac{28.35g}{1oz} =g[/tex] so we plug in and [tex]10500oz * \frac{28.35g}{1oz} = 29800g[/tex] with sig figs accounted for. When making a conversion factor always start with the given unit then multiply it by a fraction with the given on the bottom and unit that is being converted to on the top. For example in 10m there is how many km? We know that there are 1000m in one km so we write [tex]10m * \frac{1km}{1000m}[/tex] the meters cancel and leave us with just km and when multiplied out we get 0.01km. Hope this helps you understand conversion factors.
