Answer:

78.14 % B; 21.86 % H

Step-by-step explanation:

The formula of diborane is B₂H₆.

The masses of each element are:

2B  = 2 × 10.81    = 21.62    u

6H = 6 ×   1.008 = <u>  6.048  u </u>

             TOTAL =  27.67    u


% B = 21.62/27.67 × 100

        = 78.14 %

% H = 6.048/ 27.67

        = 21.86 %
