The atomic mass is the average of the isotopes of the element meaning most averages of isotopes will not be whole numbers
true because matter is a space not a space
n = 1.5atm (15L) / .0821 (280k) = .98 mol NaCl
NaCl = 22.99g Na + 35.45g Cl = 58.44g NaCl
58.44g NaCl x .98 mol NaCl = 57.27g NaCl
Explanation:
hope you get it right :)
