Answer:
0.1 mol×L
Explanation:
Concentration= MOLES of SOLUTE / Volume of SOLUTION
So all we need to is to calculate the one quantity; Volume of SOLUTION has been specified to be 150 ml
So, MOLES of SOLUTE
x 100 x 10-L = ??mol; this was our starting solution.
And final CONCENTRATION=
0.15 . mol. 5 x 100 x 10-3L/
= 0.15 mol · L-1 150 x 10 3
=0.1 mol · L
Answer:
behaviors that are passed down genetically
The force exerted on the Kite is 49.6 N.
<u>Explanation:</u>
Force is nothing but the product of pressure exerted by the wind on the kite and the area of the kite.
F = P × A
Where,
F is the Force in Newton = ?
P is the Pressure = 113 Pa = 113 N/m²
A is the Area of the Kite
A = 0.836 m × 0.525 m = 0.4389 m²
Now, we can find the force as,
F = 113 N/m² × 0.4389 m²
= 49.6 N [ ∵ In the units, m² gets cancelled]
So the force exerted on the Kite is 49.6 N.
Equal volumes of equal concentrations of strong acid and strong base are mixed. Because the volumes and molarities are equal, the number of mole NaOH and HCl are equal.
From reaction
HCl + NaOH ---> NaCl +H2O
we can see that if number of moles HCl and NaOH are equal, they will react completely, and no acid or base is going to be in solution anymore.
So, pH=7.
