9. In standardizing roughly 0.05M H, SO, solution,1.325g of pure an hydrous sodium carbonate were made up to 250cm' and 25cm' of the solution needed 23.5 cm of
the acid. Calculate the concentration of the acid in gom*. If 906cm? of the acid
were left after the titration, how many cm' of water must be added to the
remaining acid to make it exactly 0.05M?(Ans 5.212, 57.82) SOMEONE PLEASE EXPLAIN HOW TO DO IT!!

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

i'm assuming that the correct answer is indeed the first one/ "a"..

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
