Because the Tube Dilution Is the Same for All Tubes $D_{\text {sample }}=\left(D_{\text {tube }}\right) N$

Because the tube dilution is the same for all tubes in a serial dilution,the sample dilution for a given tube can be determined using which equation (in all cases N is the number of the tube in the sequence) ?

A) $D_{\text {sample }}=\left(D_{\text {tube }}\right) N$
B) $D_{\text {Sample }}=\left(D_{{tube }}\right) ^{N}$
C) $D_{\text {sample }}=\frac{V_{\text {tube }}}{N}$
D) $D_{\text {sample }}=\frac{N}{V_{\text {tube }}}$
