How many moles are present in 5.67x1025 atoms of Carbon (C)?

94 moles of Carbon

Explanation:

From the question,

Using Avogadro's constant

1  mole of every element contains 6.03×10²³ atoms of the element

If 1 mole of Carbon contains 6.03×10²³ atoms of Carbon,

Then, x mole of Carbon will contain 5.67×10²⁵ atoms of Carbon

1 mole of C ⇒ 6.03×10²³ atoms of C

x mole of C ⇒ 5.67×10²⁵ atoms of C

solve for x

x = (1× 5.67×10²⁵)/6.03×10²³

x = 94.03 moles of Carbon

x ≈ 94 moles of Carbon

a is the answer to this question

explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
