Why doesn't the density of the object change when you adjust the mass and volume of the objects?

1 answer:

6 0

Because as you change the mass the volume will change and as you change the volume the mass will change too, it's a constant ratio for each element. Mass and volume are not factors that affect the density. factors that affect the density are temperature and type of the material/element

an acid based titration was performed. it took 27.45 mL of the base, KOH, to titrate 3.115 g HBr, the acid. what was the molarit

sveticcg [70]

Answer:

Explanation:

n(HBr)=3.115/81

so, 3.115/81=0.0385mol

according to the reaction, n(HBr)=n(KOH)=0.038 mol

C(KOH)=n/V=0.0385/0.02745

0.0385/0.02745 =1.4 M

in short the answer is 1.4 M (molarity)
