Answer:
a substance that can be dissolved by a solvent to create a solution
Explanation:
Answer:
0.009
Explanation:
Molarity, a measure of molar concentration of a substance is calculated thus;
Molarity = number of moles ÷ volume
According to the provided information, mass of KCl = 0.47g, volume of water = 700ml
Using mole = mass/molar mass
Molar Mass of KCl = 39.10 + 35.453
= 74.553g/mol
Mole = 0.47/74.55
Mole = 0.0063mol
Volume of water = 700ml = 700/1000 = 0.7L
Molarity = 0.006/0.7
Molarity = 0.00857
The value of molarity rounded to three decimal places (3 d.p) = 0.009
CI- the chloride ion is the anion CI its formed when the elements gains electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.
Answer:
0.6802 mol
Explanation:
1 grams K2S = 0.00907 mol
0.00907 x 75 = 0.6802 mol
