Answer:
![\boxed{\sf Density = 2.23 \ g/mL}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Csf%20Density%20%3D%202.23%20%5C%20g%2FmL%7D%20)
Given:
Mass = 100 g
Volume = 45 mL
To Find:
Density
Explanation:
Formula:
![\boxed{ \bold{Density = \frac{Mass}{Volume}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7BDensity%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D%7D%7D)
Substituting value of mass & volume in the formula:
![\sf \implies Density = \frac{100}{45} \\ \\ \sf \implies Density = 2.23 \: g/mL](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%20Density%20%3D%20%20%5Cfrac%7B100%7D%7B45%7D%20%5C%5C%20%20%5C%5C%20%20%20%5Csf%20%5Cimplies%20Density%20%3D%20%202.23%20%5C%3A%20g%2FmL%20)
