Answer:
Option 4
Explanation:
Hydrochloric acid is a strong one, that gives protons to medium. It can be dissociated as this:
HCl → H⁺ + Cl⁻
M means Molarity. It is a sort of concentration that indicates the moles of solute in 1L of solution.
M = moles / volume (L)
We can also say M = mmoles / mL of solution
M . mL = mmoles
0.453 M . 62.85mL = 28.5 mmoles
If we divide by 1000 → 28.5 mmol . 1 mol / 1000 mmol = 0.0285
2 moles
Explanation:
Given parameters:
Mass of Sb = 243.52g
Unknown:
Number of moles = ?
Solution:
The number of moles of any substance can be calculated using the expression below:
Number of moles = 
Molar mass of Sb = 121.76g/mol
Now input the parameters:
Number of moles =
= 2 moles

Answer: 0.27 M
Explanation:
molarity = (0.350)/(1.30) = 0.27 M
