Question

a student finds the mass and volume of four mystery liquids. the data is provided.

the student knows that the density of water is 1 g/ml. which of the four mystery liquids can be correctly identified as water?
z
y
x
w

Explanation:

Step1: Calculate density of liquid W

Density formula: $
ho=\frac{m}{V}$. For liquid W, $m = 5g$, $V=5mL$. So $
ho_{W}=\frac{5g}{5mL}=1g/mL$.

Step2: Calculate density of liquid X

For liquid X, $m = 6g$, $V = 2mL$. So $
ho_{X}=\frac{6g}{2mL}=3g/mL$.

Step3: Calculate density of liquid Y

For liquid Y, $m = 2g$, $V = 1mL$. So $
ho_{Y}=\frac{2g}{1mL}=2g/mL$.

Step4: Calculate density of liquid Z

For liquid Z, $m = 8g$, $V = 2mL$. So $
ho_{Z}=\frac{8g}{2mL}=4g/mL$.

Answer:

W
