What is true about a solution of 1.0 m hf? hf has a higher [oh-] than a solution of 1.0 m hcl. hf has a lower ph than a solution of 1.0 m hcl. hf has the same ph as a 1.0 m solution of 1.0 m hcl. hf has a higher [h3o+] than a solution of 1.0 m hcl.

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
