A solution is prepared with 50.0g of HNO3 and 130.0g of H2O. It has a density of 1.21g/mL. What is the total volume (mL) of the solution?
50.0g HNO3 + 130 g H2O = 180 g total.
mass = volume x density or
volume = mass/density = 180/1.21 = ??
To find the total volume of the solution, we need to use the definition of density, which is mass divided by volume.
First, we need to calculate the total mass of the solution by adding the mass of HNO3 and H2O:
Total mass = mass of HNO3 + mass of H2O
Total mass = 50.0g + 130.0g
Total mass = 180.0g
Next, we can use the density formula to find the volume of the solution:
Density = mass / volume
Rearranging the formula, we find:
Volume = mass / density
Substituting the known values:
Volume = 180.0g / 1.21g/mL
Dividing the mass by the density, we find that the total volume of the solution is:
Volume = 148.76 mL
Therefore, the total volume of the solution is 148.76 mL.
