1.50g of NaHCO3 is dissolved in 17.1g of water. Express the solubility of NaHCO3 in grams per 100g of solvent and calculate the % composition of NaHCO3 and water.
1.50 g NaHCO3 in 17.1 g H2O. So in 100, there is
1.50 g NaHCO3 x (100/17.1) = approx 9 but you need to do it more accurately.
% NaHCO3 = (g NaHCO3/total g)*100 = (9/109)*100 = ?
%H2O = (gH2O/total g)*100 = (100/109)*100 = ?
To express the solubility of NaHCO3 in grams per 100g of solvent, we need to calculate the ratio of the mass of NaHCO3 to the mass of water.
The mass of NaHCO3 is given as 1.50g, and the mass of water is given as 17.1g.
Solubility of NaHCO3 = (mass of NaHCO3 / mass of water) * 100
Solubility of NaHCO3 = (1.50g / 17.1g) * 100
Solubility of NaHCO3 ≈ 8.77g/100g
The % composition of NaHCO3 in the solution is given by:
% composition of NaHCO3 = (mass of NaHCO3 / total mass of solution) * 100
% composition of NaHCO3 = (1.50g / (1.50g + 17.1g)) * 100
% composition of NaHCO3 ≈ 8.06%
The % composition of water in the solution is:
% composition of water = (mass of water / total mass of solution) * 100
% composition of water = (17.1g / (1.50g + 17.1g)) * 100
% composition of water ≈ 91.94%
To express the solubility of NaHCO3 in grams per 100g of solvent, we need to calculate the mass of NaHCO3 dissolved in 100g of water.
1. First, let's find the mass of NaHCO3 dissolved. We know that 1.50g of NaHCO3 is dissolved in 17.1g of water. So, the mass of NaHCO3 dissolved can be calculated as:
Mass of NaHCO3 dissolved = 1.50g
2. Now, let's calculate the solubility of NaHCO3 in grams per 100g of solvent. Since we have 17.1g of water, we can set up a proportion:
(1.50g / 17.1g) x 100 = Solubility in grams per 100g of solvent
Simplifying this equation, we get:
Solubility in grams per 100g of solvent = (1.50g / 17.1g) x 100
3. Calculate the value:
Solubility = (1.50g / 17.1g) x 100 ≈ 8.77 g/100g
So, the solubility of NaHCO3 is approximately 8.77 grams per 100 grams of water.
Now, let's calculate the % composition of NaHCO3 and water in the solution.
4. The total mass of the solution is the sum of the mass of NaHCO3 and water:
Total mass = Mass of NaHCO3 + Mass of water = 1.50g + 17.1g = 18.60g
5. Calculate the % composition of NaHCO3:
% composition of NaHCO3 = (Mass of NaHCO3 / Total mass) x 100
% composition of NaHCO3 = (1.50g / 18.60g) x 100 ≈ 8.06%
So, the % composition of NaHCO3 in the solution is approximately 8.06%.
6. Calculate the % composition of water:
% composition of water = (Mass of water / Total mass) x 100
% composition of water = (17.1g / 18.60g) x 100 ≈ 91.94%
Therefore, the % composition of water in the solution is approximately 91.94%.
