Okay so i think the answer to this is.
weight=mg
m=0.000100 g=9.80
so weight= 0.00980 kgm/s2
Hopefully thats correct (i am horrible at math)
Answer:
Yes, this answer is correct.
Explanation:
Absolute zero is -273.15 degrees celsius
T= Tc+273.15
T is the kelvin temperature
Tc is the temperature in degrees celsius
substitute;
T= -273.15 + 273.15
T=0 K

Al₂O has a higher percentage of aluminium.
Explanation:
To solve this problem, we have to compare the molar mass of the aluminium in each compound to one another as percentage of the whole compound:
Molar mass of Al₂O = 2(27) + 16 = 70g/mol
Molar mass of Al(NO₃)₃ = 27 + 3[14 + 3(16)] = 213g/mol
Percentage by mass of Al in Al₂O =
x 100 = 77%
Percentage by mass of Al in Al(NO₃)₃ =
x 100 = 12.7%
Al₂O has a higher percentage of aluminium.
