Answer:
Draw circles to represent the electron shell of each atom overlapping the circles where the atoms are bonded. Add dots to represent the outer electrons of one type of atom (H). Add crosses to represent the outer electrons of the other type of atom (Cl). Make sure the electrons are always in pairs.
<u>Given:</u>
Initial concentration of potassium iodate (KIO3) M1 = 0.31 M
Initial volume of KIO3 (stock solution) V1 = 10 ml
Final volume of KIO3 V2 = 100 ml
<u>To determine:</u>
The final concentration of KIO3 i.e. M2
<u>Explanation:</u>
Use the relation-
M1V1 = M2V2
M2 = M1V1/V2 = 0.31 M * 10 ml/100 ml = 0.031 M
Ans: The concentration of KIO3 after dilution is 0.031 M
Answer:
A) 1.3 * 10^-13
Explanation:
0.000000000000013 = 1.3 * 10^-13

Answer:
c) 1.07 M C6H1206
Explanation:
Molarity is the molar concentration of a solution, which is glucose in this case. It can be calculated using the following formula:
Molarity (M) = number of moles (n) ÷ volume (V)
Using mole = mass/molar mass, to calculate the number of moles of glucose in the solution, where mass = 125grams and MM = 180.16g/mol
mole = 125/180.16
mole = 0.694mol
Volume = 650.0 mL = 650/1000 = 0.650 L
Molarity = n/V
Molarity = 0.694/0.650
Molarity = 1.07 M
