What mass of NaCl can be dissolved in 7.50 X 10 (to the 2nd)grams of water at 25 degrees C?
In order to determine the mass of NaCl that can be dissolved in 7.50 X 10^2 grams of water at 25 degrees Celsius, we need to refer to the solubility chart for NaCl at this temperature.
The solubility of NaCl in water at 25 degrees Celsius is approximately 36 grams per 100 grams of water. To calculate the maximum mass of NaCl, we can use the following steps:
Step 1: Convert the given amount of water from grams to 100 grams.
7.50 X 10^2 grams of water is equivalent to (7.50 X 10^2) / (1.00 X 10^2) = 7.50 grams of water in terms of 100 grams.
Step 2: Use the solubility information to determine the mass of NaCl that can be dissolved in 100 grams of water.
The solubility of NaCl is 36 grams per 100 grams of water.
Step 3: Calculate the mass of NaCl that can be dissolved in 7.50 grams of water.
By using a ratio, we can set up a proportion:
36 grams NaCl / 100 grams of water = x grams NaCl / 7.50 grams of water.
To find x, cross-multiply:
100 * x grams NaCl = 36 * 7.50 grams of water
Divide both sides by 100:
x grams NaCl = (36 * 7.50) / 100
x grams NaCl = 2.70 grams
Therefore, the maximum mass of NaCl that can be dissolved in 7.50 X 10^2 grams of water at 25 degrees Celsius is approximately 2.70 grams.
To determine the mass of NaCl that can be dissolved in 7.50 X 10^2 grams of water at 25 degrees C, we need to refer to the solubility table for NaCl.
The solubility of NaCl in water is given as 359 grams per 1000 grams of water at 25 degrees C. We can use this information to find the solubility of NaCl in grams per gram of water.
First, calculate the solubility of NaCl in grams per gram of water:
(359 g NaCl / 1000 g H2O) = 0.359 g NaCl/g H2O
Now, multiply the solubility of NaCl per gram of water by the mass of water given:
(0.359 g NaCl/g H2O) * (7.50 X 10^2 g H2O) = 269.25 g NaCl
Therefore, approximately 269.25 grams of NaCl can be dissolved in 7.50 X 10^2 grams of water at 25 degrees C.
