Which solution has the same number of moles of KCl as 75.00 mL of 0.250 M solution of KCl?
luda_lava [24]

Answer:

None of them

Explanation:

The number of moles in 75ml is 0.01875moles while in 25ml is 0.004375 and in 129 ml is 0.018705.

REMEMBER: Molarity is the number of moles per litre so in order to get the number of moles you multiply the molarity of the substance by the quantity of the substance in litres.

I need to know all the answers for this homework!!!!
maw [93]

1. 100 C

2. Point B to C is the ices heat capacity

3. During the points D to E the bonds of the water molecules build up enough kinetic energy to break their intermolecular bonds (not intra), which can lead to gas.

4. Between points D and E the energy is being released the energy required is equivalent along the line.

5. Between point E and D the water is converting to water (condensation)

6. Energy is being released 2260 j/g

7. Yes, but only under extreme volumetric pressures

8. D and E or B and C

9. Freezing (the water is also becoming less dense)

10. Melting or if water already, absorbtion of energy

11. released.
