How many grams of agno3 are needed to prepare a 0.25 m solution in 500 grams of water?
question 2 options:

125 g

0.125g

21.25 g

170g

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

plz give brainliest

distance, luminosity, brightness, radius, chemical composition, and temperature
