Explanation :
First we have to calculate the mass of blueberries.
As, 1.0 mole of blueberries contains
blueberries
So, 0.75 grams of blueberries contains
blueberries
Mass of blueberries =
Now we have to calculate the number of automobiles needed.
Number of automobiles needed = 
Number of automobiles needed = 
Number of automobiles needed = 
Thus, the number of automobiles needed are, 
Answer:
84g Thus, 84g of KNO3 must be dissolve in 100 grams of water to form a saturated solution at 50 oC.
and 136 of KNO3 must be dissolve in 100 grams of water to form a saturated solution at 70 oC.
Explanation:
Chemical and physical properties are ways that scientists classify a substance. The color or mass it has are physical properties. However, chemical properties are chemical changes a substance undergoes.
