Tasya [4]
% error = \frac{|experimental - theoretical|}{theoretical} x 100%

Experimental: 2.85
Actual (theoretical): 2.70

% error = \frac{2.85-2.70}{2.70} x 100% = .055555 x 100% = 5.56%

1.) A compound is a thing that is composed of two or more (separate) elements.

2.) A compound cannot be separated easily, while its properties differ from where it originates from. It also is formed from chemical reactions.

3.) A pure substance, also known as chemical substance, is a material with constant composition and consistant properties.

4.) If a substance is not a pure substance, then it is an impure substance.

Hope this helped. :)
