- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
<h3>
Explanation:</h3>
<u>Step 1: Define</u>
3.93 × 10²⁴ molecules CCl₄
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of C - 12.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of CCl₄ - 12.01 + 4(35.45) = 153.81 g/mol
<u>Step 3: Convert</u>
- Set up:

- Multiply:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
1003.77 g CCl₄ ≈ 1000 g CCl₄
To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite risk of cancer and other diseases. Patients exposed to radiation between 8 to 30 Gy experience nausea and severe diarrhea within an hour, and they die between 2 days and 2 weeks after exposure. Absorbed doses greater than 30 Gy cause neurological damage
Answer : The correct expression is, (150 × 3 × 31.998) ÷ (232.29 × 1) grams
Explanation :
First we have to calculate the moles of 

Now we have to calculate the moles of 
The balanced chemical reaction is,

From the balanced chemical reaction we conclude that,
As, 1 mole of
react to give 3 mole of 
So,
moles of
react to give
moles of 
Now we have to calculate the mass of 


Therefore, the correct expression for the mass of oxygen gas formed is, (150 × 3 × 31.998) ÷ (232.29 × 1) grams
Answer:
a)
and 
b)
and 
c)
and 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like
,
and
These units of temperature are inter convertible.



a) 68°F (a pleasant spring day) to °C and K.
Converting this unit of temperature into
and
by using conversion factor:



b) 164°C (the boiling point of methane, the main component of natural gas) to K and °F
Conversion from degree Celsius to Kelvins and Fahrenheit



c) 0K (absolute zero, theoretically the coldest possible temperature) to °C and °F.
