How does a rock’s mass change when it goes through the rock cycle?

JulijaS [17]

The rock cycle is the process of converting rock between igneous, sedimentary, and metamorphic forms. ... Molten rock inside the Earth undergoes a phase change as it cools to produce solid igneous rock. The chemical changes which form the rock depend on the type of minerals present and how fast the rock cools.

You perform recrystallization of 1 g of impure acetanilide from water. The solubility of pure acetanilide in hot water is 55g/L.

likoan [24]

Answer:

38.32 mL is minimal volume of hot water that is needed to dissolve 2.1 g of pure acetanilide.

Explanation:

Mass of acetanilide to be dissolved in hot water = 2.1 g

Mass of hot water to be used = m

Solubility of acetanilide = 55 g/L

This means that 55 grams of acetanilide dissolves in 1 L of hot water.

Then 1 grams of acetanilide will dissolve in :

$\frac{1}{55}\times 2.1 L=0.0382 L$

0.0382 L = 0.0382 × 1000 mL =38.2 mL

1 L = 1000 mL

38.32 mL is minimal volume of hot water that is needed to dissolve 2.1 g of pure acetanilide.
