Answer:
Molarity = 3 M
Explanation:
Given data:
Volume of solution = 2 L
Number of moles of HCl = 6 mol
Molarity = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
by putting values,
Molarity = 6 mol / 2 L
Molarity = 3 M (M = mol/L)
Answer:
(B) 2AgCl + sunlight → Cl2 + 2Ag (decomposition reaction) is correct option.
Answer:
0.00731 kg
Explanation:
Given that solution is a product of solute and solvent.
Hence, solution = solute * solvent
In this case, the solution is given as 0.950 grams = 0.00095 kilograms
solute is given as 130 grams = 0.13 kilograms
Hence to get the amount of solvent in kilograms, we have
Solution ÷ Solute => 0.00095 ÷ 0.13
= 0.0073076923
=> 0.00731 kilograms
