Answer:
3M
Explanation:
Molarity is one of the measures of the molar concentration of a solution, which can be calculated by using the formula below:
Molarity = number of moles ÷ volume
From the information given in this question, 4 liters of a solution contains 12 moles of sugar. This means that n = 12mol and V = 4L
Molarity = n/V
Molarity = 12/4
Molarity = 3
Hence, the molarity of the sugar solution is 3mol/L or 3M

Answer:
He
Explanation:
From Graham's law of diffusion, lighter or less dense gas tends to diffuse faster than denser gas amongst the list, He is the lightest gas and so will diffuse faster
