I believe the answer is sugarcane
Partial pressure (N2) = mole fraction * total pressure
{ 1 mole of any ideal gas occupy same volume of 1 mole of any other ideal gas under same condition of temperature and pressure so mole fraction in the sample is simply 78.08% = 0.7808 this is because equal volume of each gas has equal moles
partial pressure N2 = 0.7808 * 760 .0
partial pressure = 593.4 mmhg ( 1 torr = 1mmhg )
-19.15 degrees Celsius. 254k-273.15=-19.15
You have to subtract 273
Your correct answer is (B) Ratio of neutrons to protons
Hope this helps! :)
Answer:
total weight to expect = 331.60 grams
Explanation:
The flask wanted to be charged with 1.6 grams of sugar. The empty flask was weighed on a balance and it was determined to weigh 330 grams . The weight we would expect when we add the sugar can be computed as follows:
weight of the empty flask = 330 grams
weight of the sugar = 1.6 grams
The weight of the flask after adding the sugar will be the sum of the weight of the sugar and the empty falsk
Therefore,
Total weight to expect = 330 grams + 1.6 grams
total weight to expect = 331.60 grams
