Answer 1

Answer:

the weight of a plastic was 3.75 before heating and 3.50g after heating what is the loss percent decrease.

Answer 2

Answer:

weigh before heating = 3.75 g

weight after heating= 3.50 g

decrease=3.75-3.50=0.25

\begin{gathered}\% = 0.25 \div 3.75 \times 100 \\ \% = 25 \div 375 \times 100 \\ \% = 6.\%\end{gathered}

%=0.25÷3.75×100

%=25÷375×100

%=6.%
