Answer:

for this one you would have to divide 19.9g by the kinetic energy 1.0 and you would get your answer.

Explanation:if you would give me brainiest that would help a lot :)

.The vapor pressure of a volatile liquid can be determined by slowly bubbling a known volume of gas through it at a known temper

Elis [28]

Explanation:

It is given that the initial mass of benznene is 7.9286 g

Mass of benzene left = 5.9987 g

So, mass of benzene with which gas get saturated will be calculated as follows.

= 7.9286 g - 5.9987 g = 1.9299 g

Therefore, moles of benzene with which gas get saturated = $\frac{mass}{ molar mass}$

= $\frac{1.9299 g}{78.112 g/mol}$

= 0.0247 moles

Temperature = $27.3^{o}C$ = 27.3 + 273.15 = 300.45 K

Volume = 5.01 L

So, according to ideal gas equation PV = nRT

Putting the given values into the ideal gas equation as follows.

PV = nRT

$P \times 5.01 L$ = $0.0247 mol \times 62.36 torr-liter/mol K \times 300.45 K$

P = $\frac{462.781 torr-liter}{5.01 L}$

= 92.371 torr

Hence, we can conclude that vapor pressure of benzene is 92.371 torr.

A gas has a volume of 590 mL at a temperature of –55.0°C. What volume will the gas occupy at 30.0°C? Show your work.

Mashutka [201]

Step 1: Convert the temperatures to K
-55 + 273 = 218 K = T1
30 + 273 = 303 K = T2

Step 2: Use the formula V1/T1 = V2/T2
590/218 = V2/303
V2 = 303 * (590/218) = 820.02 mL is the new Volume

1.00 x 10^6 atoms of gold is equivalent to how many grams?

S_A_V [24]

Answer:

3.27 x 10⁻¹⁶ grams

Explanation:

moles Au = 1.00 x 10⁻⁶ Atoms / 6.02 x 10²³Atoms / mole = 1.66 x 10⁻¹⁸ mole Au

grams Au = 1.66 x 10⁻¹⁸ mole Au x 196.97 grams Au/mole Au

= 3.27 x 10⁻¹⁶ grams Au
