How many grams of nano3 would have to be added to 100. grams of water at 45°c to make a saturated solution of this salt? 1. 100. 2. 110. 3. 120. 4. 130.

2. 110.

Explanation:

From the solubility curve, you can find that at 45°C to make a saturated solution of this salt, you should add 110 g of NaNO₃.

*tilts head* sounds more like a statement

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
