Using the accompanying chart, calculate the volume of a Densities of Group 14 Elements tin block that has a mass of 95.04 grams

saw5 [17]

<u>Answer:</u> The volume of given mas of tin block at STP is $13.0cm^3$

<u>Explanation:</u>

To calculate volume of of the substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Mass of tin = 95.04 g

Density of tin = $7.31g/cm^3$

Putting values in above equation, we get:

$7.31g/cm^3=\frac{95.04g}{\text{Volume of tin}}\\\\\text{Volume of tin}=\frac{95.04g}{7.31g/cm^3}=13.0cm^3$

Hence, the volume of given mas of tin block at STP is $13.0cm^3$
