$\text{7.85 g}$

#### Explanation:

All you have to do here is to use the fact that

$\textcolor{b l u e}{\underline{\textcolor{b l a c k}{\text{1 dag = 10 g}}}}$

In other words, you need $10$ grams in order to have $1$ decagram.

To convert your sample to grams, set up this conversion factor by adding decagrams as the denominator and grams as the numerator.

You will end up with

$0.785 \textcolor{red}{\cancel{\textcolor{b l a c k}{\text{dag"))) * "10 g"/(1color(red)(cancel(color(black)("dag")))) = color(darkgreen)(ul(color(black)("7.85 g}}}}$

The answer must retain the number of sig figs you have for your measurement.
