The effusion rate of hcl is 43. 2 cm/min in a certain effusion apparatus. What is the rate of effusion of ammonia in the same apparatus?.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
