Answer:
Explanation In order to calculate the pH, take the negative log of the hydronium ion concentration. To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.
All of the above!
By analyzing the remains of fossilized organisms (such as old animal bones or plants), scientists can approximate what the organism might have looked like and the climate/environment it lived in -- and based on that, they can try to figure out how the Earth's surface has changed over time. Also, they can use the fossil to compare it to creatures that live now to see what has changed in that species over time.
Answer:
Molarity of 40 ml of NaoH is 0.3125 mL
Explanation:
As we know
Molarity of acid * volume of acid = molarity of base * volume of base
Substituting the given values, we get
Molarity of 40 ml of NaoH is 0.3125 mL
Find the molar mass of CH3 and divide that by 45.0. That should give a whole number and then mult that whole number by CH3 to find molecular formula to get like ( incorrect ex: C2H6) which is mult by 2
The answer is (3) moles of solute per liter of solution. That is what the definition of molarity of a solution means. The equation is concentration = mol number of solute/ volume of solution.
