Answer:
boiling point is the physial property of matter
Answer:
Mass = 16.7 g
Explanation:
Given data:
Volume = 125 mL (125/1000 =0.125 L)
Molarity = 2.50 M
Mass in grams of solute = ?
Solution:
First of all we will calculate the number of moles:
<em>Molarity = number of moles solute / volume in litter</em>
2.50 M = Number of moles of solute/ 0.125 L
Number of moles of solute = 2.50 M × 0.125 L
Number of moles of solute = 0.313 mol
Grams of solute:
<em>Number of moles = mass / molar mass</em>
Mass = number of moles × molar mass
Mass = 0.313 mol × 53.5 g/mol
Mass = 16.7 g
Answer:
there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region.
