If the container is closed and the ethanol is allowed to reach equilibrium with its vapor, how many grams of liquid ethanol rema

SVETLANKA909090 [29]

Explanation:

Let us assume that the given data is as follows.

V = 3.10 L, T = $19^{o}C$ = (19 + 273)K = 292 K

P = 40 torr (1 atm = 760 torr)

So, P = $\frac{40 torr}{760 torr} \times 1 atm$

= 0.053 atm

n = ?

According to the ideal gas equation, PV = nRT.

Putting the given values into the above equation to calculate the value of n as follows.

PV = nRT

$0.053 atm \times 3.10 L = n \times 0.0821 L atm/mol K \times 292 K$

0.1643 = $n \times 23.97$

n = $6.85 \times 10^{-3}$

It is known that molar mass of ethanol is 46 g/mol. Hence, calculate its mass as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

$6.85 \times 10^{-3} = \frac{mass}{46 g/mol}$

mass = $315.1 \times 10^{-3}$ g

= 0.315 g

Thus, we can conclude that the mass of liquid ethanol is 0.315 g.

A 25.0g tin sample was placed in boiling water at 99.5 C until it had the same temperature. Afterwards, the tin sample was place

MrMuchimi

Answer : The specific heat of tin is, 0.213 J/g.K

Explanation :

Formula used :

$q=m\times c\times (T_{final}-T_{initial})$

where,

q = amount of heat lost = -399.4 J

c = specific heat capacity of tin = ?

m = mass of tin = 25.0 g

$T_{final}$ = final temperature = $24.5^oC=273+24.5=297.5K$

$T_{initial}$ = initial temperature = $99.5^oC=273+99.5=372.5K$

Now put all the given values in the above formula, we get:

$-399.4J=25.0g\times c\times (297.5-372.5)K$

$c=0.213J/g.K$

Therefore, the specific heat of tin is, 0.213 J/g.K

If a pork roast must absorb

Black_prince [1.1K]

Let us assume propane was the fuel
C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g) = 2217kJ
1 mole ofpropane produces 3 moles of CO2
heat absorbed by pork = 0.11 x 2217
= 243.87 kJ/mol
number of moles of propane = 1700kJ / 243.87 kJ/mol
= 6.971 moles
1 mole of C3H8 = 3 moles ofCO2
6.971 moles of C3H8 = ?
3 x 6.971 = 20.913 moles of CO2
Convert to grams
mass = MW x mole
= 44 x 20.913
= 920.172g of CO2 emitted

Gaseous methanol (CH4O) reacts with oxygen gas to produce carbon dioxide gas and liquid water. Balanced the equation using the l

NikAS [45]

Answer:

The sum of the coefficients in the balanced equation is 11

Explanation:

A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.

The balance reaction of combustion for methanol is:

2CH₃OH (l) + 3O₂(g) → 2CO₂(g) + 4H₂O (g)

Coefficients from stoichiometry are 2, 3, 2 and 4

Sum = 2 + 3 + 2 + 4 = 11
