Answer:
B
Explanation:
you're moving the decimal 8 spots to the left so it can only be B
Using ideal gas equation,
P\times V=n\times R\times T
Here,
P denotes pressure
V denotes volume
n denotes number of moles of gas
R denotes gas constant
T denotes temperature
The values at STP will be:
P=1 atm
T=273 K
R=0.0821 atm L mol ⁻¹
Mass of HCl given= 49.8 g
Molar mass of HCl given=36.41
Number of moles of gas, n= \frac{Given mass of the substance}{Molar mass of the substance}
Number of moles of gas, n= \frac{49.8}{36.46}
Number of moles of gas, n= 1.36
Putting all the values in the above equation,
V=\frac{1.36\times 0.0821\times 273}{1}
V=30.6 L
So the volume will be 30.6 L.
Diffusion is the net movement of a substance, this is generally from a area of high concentration to low concentration, the particles will collide or 'bounce' off one another and by random movement, will eventually spread out till they are even.
Answer:
The answer to A would be iv) 0.01 M HCL, but I'm not sure what the answer to part B is. Hope this helps.
