0.50 Molar means 0.50 moles/liter
(.5 moles/liter)/3.5 moles= 1/7 Liters
Answer:
D.) It is between groups 13 to 18 because it is a non-metal.
Explanation:
Here we can see the periodic table and what each element is.
It is a non - metal because it is gaseous.
Answer:
18.87 g
Explanation:
80.1% of 23.56 g = 18.87 g is the mass of the silver
Molarity can be defined as the moles of solute in a liter of solution. The molarity of the salt solution is 
.
<h3>What is the relation between moles and volume?</h3>
The moles are the mass of substance with respect to the molar mass. The moles and volume relationship can be expressed in terms of molarity.
The molarity can be expressed as:
The given solution has,
- Moles of salt =
- The volume of solution =
L.
Substituting the values for molarity as:
The molarity of the solution is . Thus, option C is correct.

Answer:
Eqv Pt pH = 8.73
Explanation:
HOAc + NaOH => NaOAc + H₂O
50ml(0.10M HOAc) + 50ml(0.10M NaOH) => 100ml(0.05M NaOAc) + H₂O
For neutralized system, 100ml of 0.05M NaOAc remains
NaOAc => Na⁺ + OAc⁻
Na⁺ + H₂O => No Rxn
OAc⁻ + H₂O => HOAc + OH⁻
C(i) 0.05M ----- 0M 0M
ΔC -x ----- +x +x
C(f) 0.05-x
≅ 0.05M ----- x x
Kb = Kw/Ka = [HOAc][OH⁻]/[OAc⁻] = 1 X 10⁻¹⁴/1.7 X 10⁻⁵ = (x)(x)/(0.05M)
=> x = [OH⁻] = SqrRt(0.05 x 10⁻¹⁴/1.7 x 10⁻⁵) = 5.42 x 10⁻⁶M
=> pOH = -log[OH⁻] = -log(5.42 x 10⁻⁶) = 5.27
pH + pOH = 14 => pH = 14 - pOH = 14 - 5.27 = 8.73 Eqv Pt pH
