The solubility of sodium chloride is 35.4g of water at room temperature. What mass of sodium chloride can be dissolved in 1kg of water at room temperature?
Actually the solubility of NaCl is about 359 grams/Liter
A liter of water is about a kilogram
To find the mass of sodium chloride that can be dissolved in 1kg of water at room temperature, we need to determine the maximum solubility of sodium chloride in water at that temperature.
The given solubility of sodium chloride is 35.4g of water. This means that 35.4g of sodium chloride can dissolve in 100g of water at room temperature.
To find the maximum solubility in 1kg of water, we can use the relationship between grams and kilograms. Since there are 1000g in 1kg, we can set up a proportion:
35.4g / 100g = x / 1000g
Cross multiplying, we get:
x = (35.4g * 1000g) / 100g
x = 35400g
Therefore, the mass of sodium chloride that can be dissolved in 1kg (1000g) of water at room temperature is 35400g.
