How many grams of hydrogen chloride are percent in 250cm3 of comercial 37% by mass hydro chloric acid solution? The density of the acid is 1.19gram/cm3.
To determine the mass of hydrogen chloride present in 250 cm3 of a 37% hydrochloric acid solution, you need to follow a few steps:
Step 1: Calculate the mass of the solution.
To do this, you can use the formula: mass = volume × density. Given that the density of the hydrochloric acid solution is 1.19 g/cm3 and the volume is 250 cm3, the mass of the solution can be calculated as follows:
mass of solution = 250 cm3 × 1.19 g/cm3.
Step 2: Calculate the mass of hydrogen chloride in the solution.
Since the hydrochloric acid solution is 37% by mass, it means that 37% of the mass is hydrogen chloride. You can calculate the mass of hydrogen chloride using the formula:
mass of hydrogen chloride = mass of solution × (37/100).
Step 3: Convert the mass of hydrogen chloride to grams.
The result obtained in Step 2 is likely in grams. However, if the result is in kilograms or any other unit, you need to convert it to grams.
Following these steps:
Step 1: mass of solution = 250 cm3 × 1.19 g/cm3 = 297.5 g
Step 2: mass of hydrogen chloride = 297.5 g × (37/100) = 109.975 g
Therefore, there are approximately 110 grams of hydrogen chloride in 250 cm3 of the commercial 37% by mass hydrochloric acid solution.
