Calculate the formula weight of compounds NaOH |
|
Answer» SOLUTION :a. ` 1 xx AW` or C = 12.0 AMU `1 xx AW ` of H = 1.0 amu ` 3 xx AW` of Cl `=3 xx 35.45`= `ul(106.4 " amu")` Formula weight of `CHCl_3`= `ul(119.4 " amu ")` The ansser rounded to three significant figure is 119 amu. b. IRON (III) Sulfate ` 2 xx `Atomic weight of Fe `=2 xx 55.8`=111.6 am ` 3 xx ` Atomic weight of O `= 12 xx 16 = ul(192.0" amu ")` The answer rounded to three significant figure is ` 4.00 xx 10^(2) ` amu. |
