Question

1. the masses and volumes of four different substances are shown in the table below. which substance has the lowest density? a. substance x b. substance y c. substance z d. substance t substance mass (grams) volume (cm³) substance x 500 100 substance y 1000 2000 substance z 200 25 substance t 450 50 part ii-short answer. find the density of the following object:

Explanation:

Step1: Recall density formula

Density formula is $
ho = \frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Calculate density for X

For Substance X: $m = 500$ g, $V = 100$ $cm^3$. $
ho_X = \frac{500}{100} = 5$ $g/cm^3$.

Step3: Calculate density for Y

For Substance Y: $m = 1000$ g, $V = 2000$ $cm^3$. $
ho_Y = \frac{1000}{2000} = 0.5$ $g/cm^3$.

Step4: Calculate density for Z

For Substance Z: $m = 200$ g, $V = 25$ $cm^3$. $
ho_Z = \frac{200}{25} = 8$ $g/cm^3$.

Step5: Calculate density for T

For Substance T: $m = 450$ g, $V = 50$ $cm^3$. $
ho_T = \frac{450}{50} = 9$ $g/cm^3$.

Step6: Compare densities

Compare $
ho_X = 5$, $
ho_Y = 0.5$, $
ho_Z = 8$, $
ho_T = 9$. The smallest is $
ho_Y$.

Answer:

B. Substance Y
