Answer : The correct option is, 0.21 moles
Solution : Given,
Molarity of the solution = 0.85 M = 0.85 mole/L
Volume of solution = 250 ml = 0.25 L
Molarity : It is defined as the number of moles of solute present in one liter of the solution.
Formula used :
Now put all the given values in this formula, we get the moles of solute of the solution.
Therefore, the moles of solute is, 0.21 moles
1. Transitional fossils tells a story of the relationship between the ancestors and the descendant, this allows scientists to determine or study the common pattern in development. This fossils are also used to prove the Darwin theory of evolution.
2. Yes the synonym of transitional is 'midway' and/or ;middle'. Transitional fossils are fossils that have traits of their ancestor and descendant. Thus these fossils exist between (middle) of their ancestor and descendant.
3. No, I don't think it is possible for all species that ever existed, because some fossils exist in places that humans cannot reach.
It's B. Since density equals mass/volume. The missing quantity needed is mass.Hope this helps.
