The concentration of the sodium hydroxide will be 0.016 M
<h3>Stoichiometric problem</h3>
First, the concentration of the diluted nitric acid needs to be found.
m1 = 2.0 M, v1 = 100 mL, v2 = 300.0 mL
m2 = 2 x 100/300 = 0.6667 M
The equation of the reaction goes thus:
The mole ratio is 1:1.
Mole of 0.6667 M, 7.05 mL HNO3 = 0.6667 x 0.00705 = 0.0047 mol
Equivalent mole of NaOH = 0.0047 mol
Molarity of 0.0047 mol, 30.0 mL NaOH = 0.0047/0.3 = 0.016 M

Answer:
Pollution that does not originate from a single source, or point, is called nonpoint-source pollution.
A solute is a substance that dissolves into another substance , and forms a solution.
The answer is; In the US, hydroelectric power is a more widely used energy source than geothermal energy
Of the total power produced in the US, 7% is contributed by hydroelectric sources while geothermal power contributes only 1% of this total. Hydroelectric contributed about 44% of US renewable energy sources. Both geothermal and hydroelectric plants utilize turbine to harness this energy to electricity.
Answer:
0.625mol/L
Explanation:
Given parameters:
Number of moles of solute = 5moles
Volume of solvent = 8L
Unknown:
Molarity = ?
Solution:
Molarity is the number of moles of solute per unit volume of solution. It is mathematically expressed as
Molarity =
Molarity = = 0.625mol/L
