Answer:
1.12M
Explanation:
Given parameters:
Volume of solution = 2.5L
Mass of Calcium phosphate = 600g
Unknown:
Concentration = ?
Solution:
Concentration is the number of moles of solute in a particular solution.
Now, we find the number of moles of the calcium phosphate from the given mass;
Formula of calcium phosphate = Ca₃PO₄
molar mass = 3(40) + 31 + 4(16) = 215g/mol
Number of moles of Ca₃PO₄ =
= 2.79moles
Now;
Concentration =
Concentration =
= 1.12M
Answer:
B. To Identify the half reactions for the equation
Answer:
Glucose
Explanation:
Glucose is a source of energy and it is stored in the body (in the form of glycogen) and it can also dissolve in water.
Chlorine would become a liquid. Its boiling point is around -34 Celsius so at any temperature below that it would be liquid.
