Answer 1

Answer:

% of hydrogen = 10 %

Explanation:

Given

mass of  organic compound = 0.2 g

mass of water = 0.18 g

% of hydrogen = ??

Solution

% of hydrogen = 2/ 18 X mass of water/ mass of  organic compound X 100

% of hydrogen = 2/ 18 X 0.18/ 0.2 X100

by simplifying

% of hydrogen = 10 %
