Answer:
(A) N4H6 (B) H2O (C) LiH (D) C12H26
Explanation:
The given compounds have been arranged from left to right in order of increasing percentage by mass of hydrogen.
The percent by mass of hydrogen can be calculated by mass of hydrogen in that compound divided by total mass of that compound and finally multiplying the result with 100 to obtain the required percentage.
The chemical formula for water would be simply H2O
Density = Mass / Volume
Density = 2.74g / 3.10cm³
Density = 0.88 g/cm³
