Mercury(Hg) has a density of 13.5 g/cm cubed. How much space would 50.0 g of mercury occupy?
Calculate the mass in grams, of a 3 cubic inch cube of aluminum(Al). The density of aluminum(Al) is 2.5 g/cm cubed. NOTE:(1inch cubed =16.4 cm cubed
3*16.4*2.5 = ?
123.00
To calculate the volume of a substance given its mass and density, you can use the formula:
Volume = Mass / Density
For the first question, we want to find out how much space 50.0 g of mercury would occupy. The density of mercury is given as 13.5 g/cm³. We can use the formula mentioned above to find the volume:
Volume = 50.0 g / 13.5 g/cm³
To calculate the volume of a 50.0 g sample of mercury, divide the mass by the density. The resulting volume will be in cubic centimeters (cm³).
For the second question, we want to find the mass of a 3 cubic inch cube of aluminum (Al), given that the density of aluminum is 2.5 g/cm³. However, 3 cubic inches need to be converted to cubic centimeters (cm³).
1 inch³ = 16.4 cm³
To convert the volume to cubic centimeters, multiply the volume in cubic inches by 16.4 cm³/in³:
Volume = 3 in³ * 16.4 cm³/in³
Once you have the volume in cm³, you can use the density formula to find the mass:
Mass = Volume * Density
Substitute the converted volume and the given density into the formula to find the mass in grams.
