Question

Um Béquer muito utilizado em laboratorio tem volume de 250 ml.Determine o seu volume em:

a) Centimetros cúbicos (cm³).
b)Litros 
c) Decímetros cúbicos (dm³)

Answer 1

$\large\begin{array}{l} \bullet~~\textsf{Volume do b\'equer: }\mathsf{V=250~mL} \end{array}$


$\large\begin{array}{l} \textsf{a) Sabemos que }\\\\\mathsf{1~mL=1~cm^3.}\\\\\\\textsf{Ent\~ao o volume do b\'equer em }\mathsf{cm^3}\textsf{ \'e}\\\\ \mathsf{V=250~mL}\\\\ \mathsf{V=250\cdot (1~cm^3)}\\\\ \boxed{\begin{array}{c} \mathsf{V=250~cm^3} \end{array}} \end{array}$
