Answer:
315.
Explanation:
Hello.
In this case, since the given number has five significant figures as the zero is to the right of the first nonzero digit (3), if it is required to report it with three significant figures, it is necessary to "cut" it at the first five without any rounding since the subsequent zero is less than five.
Thus the number turns out:
315
Best regards.

Explanation:
The
answer is:
glucose,
a polar organic compound
silver
nitrate, an ionic compound
<span>The two have net charges
that enable them to attract with water molecules. Water molecules are partly
charged because of the arrangement of electron clouds around the molecule. The oxygen
atom in the molecule is more electronegative
than the two hydrogens. Therefore water is able to
form electrostatic attraction forces with
the charged molecules</span>
