From ideal gas equation that is PV=nRT
n(number of moles)=PV/RT
P=760 torr
V=4.50L
R(gas constant =62.363667torr/l/mol
T=273 +273=298k
n is therefore (760torr x4.50L) /62.36367 torr/L/mol x298k =0.184moles
the molar mass of NO2 is 46 therefore density= 0.184 x 46=8.464g/l
Answer:
a) 9424797000 m3
b) 9424797000000 liters
c) 9424797000000 kg
Explanation
Cylinder has a radius of 1 km= 1000 m.
Area Cylinder = π r^2 = 3,141599* (1000m)^2 = 3141599 m2
a) Volume Cylinder= area x Height=3141599 m2* 3000 m= 9424797000 m3
b) 1000 liters= 1m3, 9424797000 * 1000 = 9424797000000 liters
c) densiy = 1000 kg/m3, or 1 kg/ liter, mass= 9424797000 lt * 1kg/lt =
9424797000 kg
It’s aluminum because electrons and protons are basically the same thing just in different places on a electron cloud and the atomic number is 13 so I think it’s aluminum.
The number of protoms tells you what position of the element on the periodic table is
