Answer is:
1: Kr.
2: Cl₂.
3: F₂.
4: O₂.
5: N₂.
6: He.
The lighter (smaller) particles move more quickly than heavier (larger) ones at the same temperature.
Calculate molar masses of the compounds:
M(Cl₂) = 70.9 g/mol; molar mass of chlorine gas.
M(F₂) = 38 g/mol, molar mass of fluorine gas.
M(He) = 4.002 g/mol; molar mass of helium.
M(Kr) = 83.8 g/mol; molar mass of krypton.
M(N₂) = 28.01 g/mol; molar mass of nitrogen gas.
M(O₂) = 32 g/mol; molar mass of oxygen gas.
Answer:
79.90amu
Explanation:
To calculate the average atomic mass of an bromine we must multiply the masses of its isotopes with the percent abundance divided by 100. Then you add them together for your answer.
50.69 ÷ 100 = 0.5069
49.31 ÷ 100 = 0.4931
78.9183361amu × 0.5069 = 40.00amu
80.916289amu × 0.4931 = 39.90amu
40.00amu + 39.90amu = 79.90amu
Ar (Cl) = 34.969 * 75.78/ 100 + 36.966 * 24.22/ 100= 35, 45 :)
Weight=mass×g=10×9.8=98N
