You can first use the ideal gas law to calculate n : p V = n R T ( 101 325 P a) ( 0.250 l) = n ( 8.314 J K − 1 m o l − 1) ( 273 K) Solving for " n " gives n = 0.011 157 7 m o l. Now we use the connection between mass m, amount of substance n, and molar mass mass M: M = m n n = m M 0.011 157 7 m o l = 1.78 g M, WebThe total mass of these would be (23 x 10) + (100 x 11) = 1330. The average mass of these 123 atoms would be 1330 / 123 = 10.8 (to 3 significant figures). 10.8 is the relative atomic mass of boron. Notice the effect of the "weighted" average. A simple average of 10 and 11 is, of course, 10.5. ethnic outdoor cushions
