You have prepared a saturated solution of x at 20∘c using 39.0 g of water. how much more solute can be dissolved if the temperature is increased to 30∘c? express your answer with the appropriate units. the following table gives the solubility of solute x in water at two different temperatures: temperature (∘c) solubility (g/100 g h2o) 20 11.0 30 23.0

for 39g water solute dissolved at 20C = solubility ( g/ 100 g H2O ) × mass of water = ( 11g / 100g H2O ) × 39g H2O = 4.29 g

amount of solute dissolved at 30 C =

               =  23 / 100 * 39 = 8.97 g

Amount of extra solute dissolved = 8.97 - 4.29 = 4.7 g

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
