Question

The density of an object is .835 g/cm3. If its volume is 34 cm3, what is the mass of the object? (Density: D = ) .02 g .41 g 28.39 g 40.72 g

Answer 1

Answer:

Given:

D=.835 g/cm3

v= 34 cm3

To find:

m=?

Formula:

D=m/v - (i)

So, to find mass rearranging the equation (i)

D x v=m

Or m=D x v

Calculation:

m= .835 g/cm3 x 34 cm3

m= 28.39 g

Result:

Hence the mass of the object will be 28.39 grams.

Explanation:

As we know that, Density of a substance is its mass per unit volume. So to find mass we have to rearrange the equation of density i.e. D=m/v into m=D x v.

Hope so this will be helpful for you.
