You have recorded the volume of hydrogen gas produced in the reaction and you have calculated the number of moles used in the first part of the experiment. Based on this information, what is the molar volume of hydrogen gas at room temperature

a chemical reaction

explanation:

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

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
