The density of pure gold (Au) is 19.3 g/cm3. What is the mass of a block of gold that measures 1.2 cm x 4.00 cm x 3.20 cm? Pleas
N76 [4]

Answer:

296.448 g

Explanation:

Density:

we know that density of an object can be measured by dividing its mass to its volume.

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m= mass

V= volume

Given data:

volume= 1.2 cm x 4.00 cm x 3.20 cm =15.36 cm3

density=  19.3 g/cm3

mass=?

Now we will put the values in the formula,

d=m/v

d x V= m

m = 15.36 cm3 x 19.3 g/cm3

m=296.448 g

so the mass of block of gold is 296.448 g

Constance has an apple that weighs 85,000 milligrams and a peach that weighs 0.15 kilograms. which fruit has the greater mass? c
Rama09 [41]

The fruit which has the greater mass is peach i.e. 150 grams.

<h3>What is mass?</h3>

Mass is a quantity which is used to define that what amount of substance will occupy any space or present in the given object.

We have given,

Weight of apples = 85,000 mg

Weight of peach = 0.15 kg

To compare the quantity first we have to convert both of these units in the same unit, and we know that:

In 1 kilogram = 1000 grams

And in 1 grams = 1000 milligrams

So, we convert both the units into grams as:

85,000 mg =  85,000 / 1000 = 85 grams

0.15 kg = 150 grams

So, the mass of peach is high.

Hence, peach has the greater mass.
