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.
Answer:
2NaOH + CO2 -> Na2CO3 + H2O
1) Find the moles of each substance
2) Determine the limitting reagent
∴ Carbon dioxide is limitting as it has a smaller value.
3) multiply the limiting reagent by the mole ratio of unknown over known
n(H2O ) = 0.3976369007 × 1/2
= 0.1988184504 moles
4) Multiply the number of moles by the molar mass of the substance.
m = 0.1988184504 × (1.008 × 2 + 16.00)
= 0.1988184504 × 18.016
= 3.581913202 g
