Astock bottle of an acid reads: 56% by mass and 1.25 specific gravity. if the molar mass of the acid is 70g, find the mole per cubic decimeter

Explanation:

Cubic decimeter is the same unit as liter; so, mole per cubic decimeter is mole per liter, and that is the unit of concentration of molarity. Thus, what is asked is the molarity of the solution. This is how you find it.

1. Take a basis: 1 dm³ = 1 liter = 1,000 ml

2. Calculate the mass of 1 liter (1,000 ml) of solution:

Here, the density is given through the specific gravity

Scpecific gravity = density of acid / density of water

Take density of water as 1.00 g/ml.

3. Calculate the mass of solute (pure acid)

4. Calculate the number of moles of solute:

5. Calculate molarity (mol / dm³)

did anyone actually do this? like if anyone has submitted this i rly need .

since electrons are negative the answer is neagtaive
