The density of lead is 11.4g/cm^3 at 25 degrees C. Calculate the volume occupied by 25.0g of lead
ElenaW [278]

Answer:

2.193 cm³

Step-by-step explanation:

density is mass divided by volume:

density =  \frac{mass}{volume}

you can manipulate the formula by multiplying with volume:

density \times volume = mass

then dividing by density:

volume =  \frac{mass}{density}

in this case:

volume =  \frac{25g}{11.4 \frac{g}{cm}  }  = 2.193 { \: cm}^{3}
