A label on a bottle of HCL has the following information,density 1.134gm^-3 and % purity 37%. Find the mass of HCl in 1cm^3 of the stock solution.plz explain in detail
thanks alot
1.134 g/cc x 1 cc x 0.37 = ?
explanation:
1.134 g/cc x 1 cc = mass in g of the solution in 1 cc but this is in the solution and not pure HCl.
That x 0.37 is the mass of HCl since it is only 37% HCl.
Which is the answer
Find the number of moles of HCL in 1 centimeter cubic of the solution

To find the mass of HCl in 1cm^3 of the stock solution, you need to consider the density and the percentage purity of the solution.
Step 1: Calculate the mass of 1cm^3 of the stock solution.
The density of the stock solution is given as 1.134 gm^-3. This means that 1 cm^3 of the solution has a mass of 1.134 grams.
Step 2: Calculate the mass of HCl in 1cm^3 of the stock solution.
The percentage purity of the solution is given as 37%. This means that 37% of the weight of the stock solution is pure HCl.
To find the mass of HCl in 1cm^3 of the stock solution, you need to calculate 37% of the mass of the stock solution.
Mass of HCl in 1cm^3 = Percentage purity * Mass of the stock solution
Mass of HCl in 1cm^3 = 37% * 1.134 grams
Now, let's calculate the value:
Mass of HCl in 1cm^3 = 0.37 * 1.134 grams
Mass of HCl in 1cm^3 = 0.41958 grams
Therefore, the mass of HCl in 1cm^3 of the stock solution is approximately 0.41958 grams.
