The minerals?
when an acid reacts with a base it forms salts depending on the acids and bases reacted it will determine its formula
for example HCl + NaOH = NaCl + H20
hope that helps
Answer:
A
Explanation:
2.60 g of CoCl2 was dissolved in water to make 100 mL of solution.
Number of moles of CoCl2 dissolved = mass/molar mass
= 2.60/130
= 0.02 mole
Molar concentration of solutions = number of moles/volume (dm3)
= 0.02/0.1
= 0.200 M
Hence, the molar concentration of thesolution is 0.200 molar.
Correct option = A
