Answer #1

Four measurements of molamass are 30.7, 29.6, 31.1 and 32.Og/mole a) Average mass of the Compound(X) Average mass of the Compoundx30.7+29.6+31.1+320 b) 30.7+29.6+31.1+32.0 = 30.85 g / mol (X-307)+(X-29.6) +(X-31.1)+(X-320) Standerd deviati on(S) (3085-30.7)?+(30.85-29.6)+(30.85-31.1 (30.85-32.0 Standerd deviati on- 0.0225+1.5625+0.0625+1.3225 ? Standerd deviation 0.995 100 0.995 3.225290 Relative Standerd deviation (RSD) eviation R.SD)-30.85 -= 3.2252%
