A 2.026g sample of a hydrate of sodium carbonate (Na2CO3) is heated to remove water. After heating, the mass of the sample is 0.
OLEGan [10]

Answer:

62.98 % of the sample of hydrate is water

Explanation:

Step 1: Data given

Mass of the sample of a hydrate of sodium carbonate (Na2CO3) = 2.026 grams

After heating, the mass of the sample is 0.750 g

Molar mass H2O = 18.02 g/mol

Step 2: Calculate mass of water

Mass water = mass of hydrate - mass of sample after heating

Mass water = 2.026 grams - 0.750 grams

Mass water = 1.276 grams

Step 3: Calculate mass % percent of water

Mass % of water = (mass of water / total mass hydrate) * 100 %

Mass % of water = (1.276 grams / 2.026 grams) *100 %

Mass % of water = 62.98 %

62.98 % of the sample of hydrate is water

When would it be most appropriate to use ppm to describe the concentration of the solutes in a solution?
cluponka [151]

B) When describing very dilute solutions.

Explanation:

The most appropriate time to use ppm is when describing dilute concentrations of solutes in solutions. It is used mostly to determine trace amount of elements in water and soils.

  • The part per million ppm is the amount of miligram of a solute in a liter of solution.
  • It is similar to percentage.
  • Minute and trace concentrations are very difficult to work with.
  • Using parts per million, they become better appreciated and easy to use.
