Question

Specific gravity of HCl is 1.08. what is its Molarity???

Answer 1

Answer:

Here's what I got.

Explanation:

Before doing anything else, make sure that you have a clear understanding of what specific gravity means.

Specific gravity usually refers to the ratio between the density of a given substance and the density of a reference substance at the same temperature. More often than not, that reference substance is water.

SG=ρsubstanceρwater

Since no mention of temperature was made, you can assume the density of water to be equal to 1.00 g/mL.

In this context, hydrochloric acid's specific gravity tells you what the density of a specific hydrochloric acid solution is compared with that of water.

More specifically, the density of your hydrochloric acid solution will be equal to

SG=ρHClρwater⇒ρHCl=SG×ρwater

ρHCl=1.08×1.00 g/mL=1.08 g/mL

So, you know what the density of the solution is. To find its molarity, you need to pick a sample of this solution and figure out how many moles of hydrochloric acid it contains.

Now, you're going to need the percent concentration by mass of
