There are 64 squares in 1 chess board. 4 chessboards = 1 go board If I have 20. go boards, how many squares is that? Write the number value only in the
first answer box and the units only in the second answer box. Remember to adjust for sig
figs.

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
