The effusion rate is 1.125 cm/sec for ammonia.
How to find effusion rate ?
Effusion rate (r1) HCl = 43.2 cm/min
Molar mass (m2) NH3 =17.04g/mole
Molar mass (m1) HCl =36.46g/mole
- Substitute the molar masses of the gases into Graham's law and solve for the ratio.
firstly convert 43.2 cm/min into cm/sec i.e., 0.72 cm/sec
Then,
0.72/r2 =√17.04/36.46
r2= 1.125 cm/sec
Hence, the rate of diffusion of ammonia is 1.125 times faster than the rate of diffusion of hydrogen chloride.

Explanation:
12 is the electron number of magnesium
Answer:
The strength of an acid refers to how quickly the hydrogen ions present are able to dissociate. The concentration of an acid refers to the amount of hydrogen ions present compared to water. Therefore, an acid can be described as both strong and dilute as it may have less hydrogen ions that dissociate quickly.
