0.50g of a volatile liquid was introduced

Chemistry
1 answer:
Lyrx [107]3 years ago
5 0

Answer:

59.52g/mol

Explanation:

This question can be answered using the formula;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

R = gas constant (0.0821 Latm/molK)

T = temperature (K)

From the information provided:

P = 190mmHg = 190/760 = 0.25atm

V = 1000ml = 1000/1000 = 1L

n = number of moles = ?

T = 91°C = 91 + 273.15 = 364.15K

PV = nRT

0.25 × 1 = n × 0.0821 × 364.15

0.25 = 29.8967n

n = 0.25/29.8967

n = 0.0084mol

Mole = mass/molar mass

Molar mass = mass/mole

Molar mass = 0.50/0.0084

Molar mass = 59.5238

Hence, the molecular mass of the liquid is 59.52g/mol

The best thermometer to use where temperatures drop below -39°C (-38.2°F) is:_______.
xxTIMURxx [149]

Answer:

The best thermometer to use for this temperature is the alcohol-in-a -glass thermometer.

Explanation:

The alcohol thermometer is a type of thermometer which uses ethanol as its thermometric liquid. This has some advantages at low temperatures because ethanol freezes at about −114.9 °C  that is (−174.82 °F).

Due to its low freezing point, it can still function effectively as a thermometric liquid, expanding and contracting properly based on the applied heat,  when dealing with temperature measurements that are at about -38.2°F.

Given: N2 + 3Cl2 → 2NCl3, ΔH = 464 kJ/mol Use the given bond energies and the periodic table to calculate the energy change in t
guapka [62]

The given chemical reaction is:

N_{2}+3Cl_{2}-->2NCl_{3}

ΔH^{0}_{reaction}=∑BE(reactants)-∑BE(products)

                 = {(941 kJ/mol) + (3 * 242 kJ/mol)} -[{2*(3*200 kJ/mol)}]

                     = 467 kJ/mol

Calculating the change in heat when 85.3 g chlorine reacts in the above reaction:

Moles of chlorine = 85.3 g Cl_{2}* \frac{1 mol Cl_{2}} {70.91 g Cl_{2}  }

                             = 1.20 mol Cl_{2}

Heat change when 1.20 mol chlorine reacts

                             = 1.20 mol * \frac{467kJ}{mol} =560.4 kJ
