Explanation:
In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
Answer:
Molarity = 0.08 M
Explanation:
Given data:
Mass of ZnCl₂ = 4.89 g
Volume of water = 500 mL (500 mL× 1L/1000 mL= 0.5 L)
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of mole ZnCl₂:
Number of moles = mass/molar mass
Number of moles = 4.89 g/ 136.3 g/mol
Number of moles = 0.04 mol
Molarity:
M = 0.04 mol / 0.5 L
M = 0.08 M
