Answer:
Weight of element X = 14.01 gram
Explanation:
Mass percentage is calculated by using :
Mass of O = 16.0 gram
let mass of X = X grams = ?
Mass of XO2 = mass of X + 2(mass of O)
Mass of XO2 = X + 2(16)
Mass of XO2 = X + 32
Total mass of O in the compound = 2(16) = 32 grams
Percent O = 69.55 %
weight of element X = 14.01 gram
14.01 is mass of nitrogen N
The correct formula of this element is NO2
