Sedaia [141]2 years ago
3 0

<em>Answer </em>

<em>no</em><em>. </em><em>of</em><em> </em><em>moles</em><em> </em><em>=</em>

<em>\frac{mass \: {g} \: }{ \: molecular \: wight}</em>

so, <em>mass</em><em> </em><em>(</em><em>g</em><em>)</em><em>=</em><em> </em><em>no</em><em>. </em><em>of</em><em> </em><em>mol</em><em>es</em><em> </em><em>×</em><em> </em><em>molecular </em><em>wight </em>

Explanation:

Li molecular wight equal to 6.941

mass (g)=3.29×104 <em>mol</em><em> </em><em>×</em><em>6</em><em>.</em><em>9</em><em>4</em><em>1</em><em> </em><em>=</em><em>2</em><em>3</em><em>7</em><em>4</em><em>.</em><em>9</em><em>3</em><em>g</em><em> </em><em>of</em><em> </em><em>lithium </em>

Fill in the blanks: Electrons are ___ in an ionic bond, whereas they are___ in a polar covalent bond, and ___ in a nonpolar cova
NNADVOKAT [17]

Answer:

The correct answer is "transferred; unequally shared; equally shared".

Explanation:

Ionic bonding occurs when a positively charged atom (cation) interacts with a negatively charged atom (anion). In ionic bonding, the cation transfers its electron to the anion. In polar covalent bonding, electrons are unequally shared. This means that the electrons spend more time in an atom than the other, which gives partial positive and negative charges to the atoms. On the other hand in nonpolar covalent bonding, the electrons are equally shared and no charges are created.

A 1.450 g sample of an unknown organic compound , X, is dissolved in 15.0 g of toluene
muminat

Answer:

Molecular weight of the compound = 372.13 g/mol

Explanation:

Depression in freezing point is related with molality of the solution as:

\Delta T_f = K_f \times m

Where,

\Delta T_f = Depression in freezing point

K_f = Molal depression constant

m = Molality

\Delta T_f = K_f \times m

1.33 = 5.12 \times m

m = 0.26

Molality = \frac{Moles\ of\ solute}{Mass\ of\ solvent\ in\ kg}

Mass of solvent (toluene) = 15.0 g = 0.015 kg

0.26 = \frac{Mole\ of\ compound}{0.015}

Moles of compound = 0.015 × 0.26 = 0.00389 mol

Mol = \frac{Mass\ in\ g}{Molecular\ weight}

Mass of the compound = 1.450 g

Molecular\ weight = \frac{Mass\ in\ g}{Moles}

Molecular weight = \frac{1.450}{0.00389} = 372.13\ g/mol
