Unfortunately, you haven't shared any data list which would make braunly users able to help you. The only thing I can suggest you is to write the neutralization reactions, this can make you understand the calculations more or less clearly. Please, next time check your attachments carefully.
Answer:
Quantity A is weight and Quantity B is mass
Explanation: weight has same unit as force. Mass is the quantity of matter present in a body or object
Answer:
1.52 M
Explanation:
Molarity of a solution is calculated as follows:
Molarity = number of moles (n) ÷ volume (V)
Based on the information given in this question,
Volume of soda (V) = 9.13 L
number of moles = 13.83 mol
Molarity = 13.83 ÷ 9.13
Molarity = 1.52 M
If I am correct the answer would be iron and nickel.
Answer:- 544.5 mL of water need to be added.
Solution:- It is a dilution problem. The equation used for solving this type of problems is:

where,
is initial molarity and
is the molarity after dilution. Similarly,
is the volume before dilution and
is the volume after dilution.
Let's plug in the values in the equation:



Volume of water added = 907.5mL - 363mL = 544.5 mL
So, 544.5 mL of water are need to be added to the original solution for dilution.
