Answer:
2.5 %
Explanation:
Considering:
Or,
Given :
For
:
Molarity = 0.2850 M
Volume = 63.30 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 63.30 × 10⁻³ L
Thus, moles of
:
Moles of
= 0.0180405 moles
Moles of
= Moles of 
Thus, Moles of
= 0.0180405 moles
Molar mass of
= 35.453 g/mol
Mass = Moles * Molar mass = 0.0180405 moles * 35.453 g/mol = 0.6396 g
Volume of sea water = 25.00 mL
Density = 1.024 g/mL
Density = Mass / Volume
Mass = Density * Volume = 1.024 g/mL * 25.00 mL = 25.6 g
<u>Mass percent of Cl⁻ = 2.5 %</u>
Answer:
the land is heated through radiant energy,
Explanation:
When water in a river or stream moves quickly, it can lift up rocks from the bottom of that body of water. When the rocks drop back down they bump into other rocks, and tiny pieces of the rocks break apart
There really isn't a difference if you think about it
