Answer:
Extinction
Explanation:
When a species becomes extinct, every last specimen has died out
Osmotic pressure is calculated by the product of the concentration in molarity, the temperature, the vant Hoff factor (3 for CaCl2 and 1 for sucrose) and R, universal gas constant. At the same temperature, the osmotic pressures of both solutions are equal.
π = CRTi
For CaCl2,
π = (1)RT(3) = 3RT
For sucrose,
π = (3)RT(1) = 3RT
1 is D 2 is c 3 is A and 4 the nucleus is so big because it is one of our largest cells in our body... hope this helps!!!!!!!!!!!
Answer: There are 
molecules present in 183.2 grams of 
gas.
Explanation:
Given: Mass = 183.2 g
Number of moles is the mass of substance divided by its molar mass.
As molar mass of water is 18 g/mol. Therefore, moles of are calculated as follows.
According to the mole concept, there are 
molecules present in one mole of a substance.
Hence, molecules present in 10.17 moles are calculated as follows.
Thus, we can conclude that there are molecules present in 183.2 grams of gas.
