PLEASE HELP I HAVE LIMITED TIME!!
n200080 [17]

Answer:

Explanation:

Si tomamos en cuenta el peso molecular del agua, que es equivalente a:

1 Átomo de H₂O

O = 16 gr/mol

H = 1 gr/mol

H₂O = 18 gr/mol

Teóricamente sabemos que en 1 mol de H2O habrá 18 gr.

 

Para obtener los moles presentes en 1 mg de H₂O, (como 1 gr = 1000 mg), decimos:

1 mol H2O …………………………..  18000 mg

       X          ……………………………   1 mg

X = 1 / 18000 = 5,56 X 10⁻⁵ moles de H20

 

Y para obtener la cantidad de moléculas presentes, de acuerdo a los moles, multiplicamos por el número de Avogadro (6,023 X 10²³ moléculas /mol)

Moléculas de H₂O = 5,56x 10⁻⁵ mol x 6,023 x 10²³

Moléculas de H₂O = 3,34488 x10¹⁹ moléculas de H₂O

En el copo de nieve habrá 3,34488 x 10¹⁹ moléculas de H₂O.

Espero que te sirva =)

Student prepares a 0.207 g sample of the nonvolatile solute caryophyllene by dissolving the substance in 1.00 g of chloroform (K
Sergeeva-Olga [200]

Answer: 204.2 g/mol

Explanation:

Elevation in boiling point is given by:

\Delta T_b=k_b\times m

\Delta T_b =  Elevation in boiling point =  3.68^0C/m

k_b = boiling point constant  = 3.63^0C/m

m = molality

Molality=\frac{n\times 1000}{W_s}

where,

n = moles of solute = \text {given mass}{\text {molar mass}}=\frac{0.207}{M}

 W_s = weight of solvent in g  = 1g

Molality =\frac{0.207\times 1000}{M\times 1g}

Putting in the values we get,

3.68=3.63\times \frac{0.207\times 1000}{M\times 1g}

M=204.2g/mol

The molar mass of caryophyllene is 204.2 g/mol.
