26. If a saturated solution of AgNO3 at 20°C contains 216 g AgNO3 per 100.0 g of water, what mass of water could
givi [52]

335.6g of water will hold 725 grams of silver nitrate.

<h3><u>Explanation:</u></h3>

The saturated solution of a solvent is the solution which can't hold more of the solvent at a particular temperature and pressure under normal conditions, if more solvent are added, it will precipitate out.

Silver nitrate solution at the particular temperature and pressure contains 216 grams of silver nitrate in 100g of water.

So, 1 gram of silver nitrate is held in 100/216 grams of water.

So, 725grams of silver Nitrate is held in 100*725/216 grams of water = 335.6 grams of water.

This gives the saturated solution of silver nitrate again.

Inga [223]

Answer:

polar

Explanation:

because carbon and sulfur have different electronegativities, the S=C bond is polar.

The entire molecule is nonpolar however because the dipoles (polar bonds) cancel out due to the geometry of the molecule (linear)
