Lead has a density of 11.3 gcm3 and a mass of 282.5 g What is its volume?

p = m/V
11.342g/mL = 200g/V
V = 200g / 11.342g/mL
V = 17.63 mL

∙ 14y agod=m/v and m/d=v so 282.5g/11.3gcm3= 25cm3 don't forget to use units. If you set the problems up with units then you will always get the right answer. IF the units don't work the problem is probably incorrect.

∙ 14y agoStart out with your Density formula D= m/V Where D=Density m= Mass in grams and V= volume.
Rearrange the equation to get V= m/D.
Fill in the numbers, V= 282.5g/11.3g/cm^3.
The grams will cancel out giving you 25cm^3

∙ 14y agoI suspect you have got your units a bit muddled up somewhere along the line.
Density is a ratio of mass per unit volume eg pounds per cubic foot or kilograms per cubic metre.
I can only guess at how the question should read -
Assuming the details should read -
Density = 11.3g/cm3 and mass = 282.5g, then the volume would be 282.5 divided by 11.3 which gives a volume of 25cm3.
Hope this helps.

∙ 13y agomass=density x volume
The mass is m the denisty is 11.3gml and 291ml-207ml is the volume
m=11.3gml x 84
m=949.2

If an object has density of 19.3 gcm3 and the volume is 10 cm3 what is the mass?
I took the liberty of changing the density to 5g/cm3 since 5g would be a mass quantity, and the volume to 10cm3, since 10cm would be a length quantity. density = mass/volume mass = density x volume = 5g/cm3 x 10cm3 = 50g
Density is defined as the mass per unit volume The density of ice is 0.92 gcm3 An ice cube 1.0 inch on a side has a mass of?
density = 0.92 g/cm^3 = 12.718 g/in^3 (1 in = 2.4 cm) vol = 1 in^3 mass = density x vol = 12.718 g
Which object will sink in freshwater which has a desity of 1.0 gcm3?
Any object with a density greater than 1.0 gmcm3.
How do you say gcm3?
g/cm3 means grams per centimeter cubed. it is the unit used in chemistry and science and math referring to Density. for example, aluminum has a density of 2.70 g/cm^3. Hopefully you can understand. :)
The density of air is 1 kgm3 What is the density of air in gcm3?
Convert: 1kg/m3 to g/cm3 1kg=1000g 1m3=100*100*100=1000000cm3 therefore: 1000g/1000000cm3 = 0.001g/cm3 4200kg/m3 * 0.001g/cm3 = 4.2g/cm3

Suppose a symmetrical metal rod of the element lead has a density of 11.4 gcm3. If this rod is cut in half the density of each piece is now 5.7 gcm3.?
The density is an intensive property; the density of lead remain unchanged in every piece of lead from this rod.
