The mass of calcium hydrogen carbonate that would be found in 52.0L of hard water in a bathtub is _______________ g.

The amount concentration of calcium hydrogen carbonate in the hard water is __________mmol/L

I do not like

200 ppm Ca(HCO3)2 is 200 mg/L. In 52.0 L there will be 200 mg/L x 52.0 L = ?? mg. Convert that to grams.

200 ppm is 200 mg/L which is 0.200g/L. Convert 0.200 g Ca(HCO3)2 to moles (moles = grams/molar mass), then to mmoles.

You don't provide enough information to solve this problem.

To determine the mass of calcium hydrogen carbonate in the given volume of hard water, we need to know the concentration of calcium hydrogen carbonate in the water. Once we have the concentration, we can use the formula:

Mass = Volume × Concentration

To find the amount concentration of calcium hydrogen carbonate, we need to know the molar mass of calcium hydrogen carbonate. The molar mass is the sum of the atomic masses of all the atoms in one mole of the compound, which can be found on the periodic table. The formula for calcium hydrogen carbonate is Ca(HCO3)2.

Molar mass of Ca = 40.08 g/mol
Molar mass of HCO3 = (1.01 + 12.01 + (3 × 16.00)) g/mol = 61.02 g/mol

Therefore, the molar mass of calcium hydrogen carbonate (Ca(HCO3)2) is:
Molar mass = (1 × 40.08) + (2 × 61.02) g/mol

Once we have the molar mass, we can calculate the amount concentration of calcium hydrogen carbonate using the formula:

Amount Concentration = (Mass Concentration ÷ Molar Mass) × (1000 ÷ Volume)

We also know that amount concentration is expressed in millimoles per liter (mmol/L). Thus, we can express the units as:

Amount Concentration (mmol/L) = (Mass Concentration (g/L) ÷ Molar Mass (g/mol)) × 1000

Now let's calculate:

1. Determine the mass of calcium hydrogen carbonate in the given volume of hard water (52.0 L):

Mass = Volume × Concentration

Note: We do not have the concentration of calcium hydrogen carbonate, so we can't calculate the mass.

2. Determine the amount concentration of calcium hydrogen carbonate in the hard water:

Amount Concentration (mmol/L) = (Mass Concentration (g/L) ÷ Molar Mass (g/mol)) × 1000

Note: We do not have the mass concentration of calcium hydrogen carbonate, so we can't calculate the amount concentration.

Unfortunately, without the concentration of calcium hydrogen carbonate in the water, we cannot find the mass or amount concentration required.
