Olivia has 6.809 Kg when we add the silver which is 247g, brass i.e. 352g and copper which is 621dag which is equals to 6210g. 1 dag is equals to 10 grams.

When 90g is converted into cg so we get 9000 g whereas when 32hg is converted into cg we get 320000 g so by adding both values we get 329000 g or 32.9 cg. By adding all three values we get 5785483000 so when we convert into scientific notation we get 5.785483 X 10¹⁰.
