Question

Are these correct?
A candle has the mass of 10 g and a volume of 16 cm3. What is it’s density(g/cm3)? .16g/cm3

A ball has the mass of 3 g and a volume of 9 cm3. What is it’s density (g/cm3) 3g/cm3

A computer has a mass of 20 g and a volume of 40 cm3. What is it’s density (g/cm3) 2g/cm3

What is the volume of a box with the density of 250 g/cm3 and a mass of 30 g? 8.3cm3

If any wrong I need help find how to do it

Answer 1

Density is =Mass/Volume

Answer 2

all are wrong

Answer 3

in most of cases you have done volume/mass

please correct it

Answer 4

if you do mass over volume you get what I got?

Answer 5

10/16=0.625
3/9=0.33
20/40=0.5
30/250=0.12

Remember always density values will be less than one for most of organic solvent
some are exceptions are there
