Question

1. what is the mass if an object takes up 15 mL of space with a destiny of 3 G / milliliters 2.find volume if Destiny is 4 gram in mass is 2 grams 3.what is the destiny of the mass is 9 grams and the volume is 12 ml

Answer 1

1)

The volume of object, V=15 mL.

The density of object, D= 3g/mL.

The mass of the object is,

`\begin{gathered} \text{Mass}=\text{Volume}* Density \\ M=V* D \\ =15\text{ mL}*3\text{ g/mL} \\ =45\text{ g} \end{gathered}`

Therefore, the mass of the object is 45 g.

2)

Density, D=4 g/mL, Mass, M=2 g.

The volume of the object is,

`\begin{gathered} \text{Volume}=\frac{\text{Mass}}{Density} \\ V=(M)/(D) \\ =\frac{2g}{4\text{ g/mL}} \\ =0.5\text{ mL} \end{gathered}`

Therefore, the volume of the object is 0.5 mL.

3)

Mass, M=9 g, Volume, V=12 mL.

The density of the object is,

`\begin{gathered} D=(M)/(V) \\ =\frac{9\text{ g}}{12\text{ mL}} \\ =0.75\text{ g/mL} \end{gathered}`

Therefore, the density of the object is 0.75 g/mL.
