Answer: 1.1739*10²⁴ molecules

Explanation:

Using Avogadro's constant,

1 mole of any substance = 6.02*10²³ molecule/atom or particles.

Therefore 1.95 mole of water contains;

1.95 * 6.024*10²³ molecules = 1.1739*10²⁴ molecules.

Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules<span> of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅</span>6.022<span>⋅1023molec.1mole H2O =1.635⋅1024molec.</span>

Afina-wow [57]

Answer:

Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.

Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity

Label the slightly negative and slightly positive parts of the water molecule. Use this illustration to explain polarity.
Daniel [21]
The water molecule is a polar molecule which would mean that there is an uneven distribution of charges. Each molecule of water has partial positive and partial negative end.  The partial positive charges is found in the H atoms while the partial negative is at the O atom. This is due to the the unequal sharing of the electrons.
