Magnox reactors (uk) are cooled with pressurized co2 gas. at a pressure of 7 bars and a temperature of 140 celsius, the gas density is rho = 0.0091 g/cm3. you may assume that the molar mass of co2 is 44 g/mol.
what is the atom density of c and o?

Letter a, because when there are unlike charges they will always attract to each other.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2

Year  1936,  lehman predicted that the earths 'inner core' is solid. she observed that the seismic signals during her study were bent and did not pass through instead bouncing back. later it was confirmed that the earth's inner core was solid made up of nickel-iron and had a molten outer core.
