How many grams of solute are needed to make 2.66L of a 1.99M C 12 H 22 O 11 solution?

1812g

Explanation:

So molarity is moles/litres or M= mol/liter (lets apply this formula to find moles)

M=mol/L

1.99=mol/2.66

Moles= 5.2934 moles of C12H22O11

Next step is quite simple, we know molar mass of C12H22O11 is 342.3 g/mol so we simply multiply the moles we get to molar mass we are left with the grams needed,

5.2934 moles of C12H22O11 * 342.3 g C12H22O11 /mol = 1812g

(I have left out decimal places, you can caculate this and add them if you desire)

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
