Molar mass NaCl = 58.44 g/mol
number of moles:
mass NaCl / molar mass
145 / 58.44 => 2.4811 moles of NaCl
Volume = 3.45 L
Therefore :
M = moles / volume in liters:
M = 2.4811 / 3.45
M = 0.719 mol/L⁻¹
hope this helps!
Answer:
Infrared thermography
Explanation:
Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. ... We call our equipment as infrared thermography considering such generalization of the terminology.
Isotonic refers to a solution having the same water potential as compared to another solutions such that there is no net movement of water molecules across a membrane when these two solutions are put together
1 gram = 1000 mg
=>
1 mg = 1/1000 g
25 mg = 25* (1/1000) g = 25/1000 g = 0.025g
