Answer:
Mass = 3732.62 g
Explanation:
Given data:
Number of formula units = 8.53×10²⁴
Mass of sample = ?
Solution:
1 mole of any substance contain 6.022×10²³ formula units.
8.53×10²⁴ formula units ×1 mol / 6.022×10²³ formula units
1.42×10¹ mol
14.2 mol
Mass of magnesium phosphate:
Mass = number of moles × molar mass
Mass = 14.2 mol × 262.86 g/mol
Mass = 3732.62 g
Asnwer :When 1 molecule of calcium phosphate is added to water, total 5 ions are formed 3 ions of Calcium(
) and 2 ions of Phosphate(
)
Explanation : When Calcium phosphate is added to water it gets dissociated into ions. Calcium phosphate (
) dissociates into 3 ions of Calcium and 2 ions of Phosphate .
Dissociation equation of calcium phosphate is :
From the dissociation equation we can conclude that total 5 ions are formed when 1 molecule of calcium phosphate is added to water.
A major problem associated with the incomplete combustion of soft coal is pollution. True
Answer:
Melting and Boiling Point Determination
The physical properties of a substance can be used to establish its purity. These properties include the melting point and boiling point. Different substances tend to have different melting and boiling points, and any pure substance will have a specific melting and boiling point.
