Answer:
Explanation:
The solution of known concentration is expressed as molarity. Molarity is the mole fraction of solute (i.e. the dissolved substance) per liter of the solution, Molarity is also commonly called molar concentration.
Mathematically;
![\mathtt{Molarity = \dfrac{moles \ of \ solute}{ liters \ of \ solution}}](https://tex.z-dn.net/?f=%5Cmathtt%7BMolarity%20%3D%20%5Cdfrac%7Bmoles%20%5C%20of%20%5C%20solute%7D%7B%20liters%20%5C%20of%20%5C%20solution%7D%7D)
To copy and complete the road map from the given question, we have the following array:
Volume A (L)
↓
d. multiplied by the molarity of A
↓
moles A
↓
b. multiplied by the moles of B / moles of A
↓
moles B
↓
c. divided by the molarity of B
↓
volume B (L)
Answer: Crystals differ in physical properties, i.e., in hardness, cleavage, optical properties, heat conductivity, and electrical conductivity.
These properties are important since they sometimes determine the use to which the crystals are put in industry.
hope this helps :)
Answer:
178.5g of NaCl is the maximum amount that can be dissolved
Explanation:
Solubility is defined as the maximum amount of solute that can be dissolved in aAt 20°C, the solubility of NaCl is 35.7g per 100g of water at 20°C. That means the maximum amount that can be dissolved of NaCl is:
500g water * (35.7g NaCl / 100g water) =
<h3>178.5g of NaCl is the maximum amount that can be dissolved</h3>
