Answer:

34.44 g.

Explanation:

  • The balanced equation for the reaction is:

<em>Fe + S → FeS,</em>

<em></em>

<em>It is clear that 1.0 mol of Fe reacts with 1.0 mol of S to produce 1.0 mol FeS.</em>

<em />

  • We need to calculate the no. of moles of 60 grams of iron and 90 grams of iron sulfide:

no. of moles of Fe = mass/atomic mass = (60.0 g)/(55.845 g/mol) = <em>1.074 mol.</em>

<em>no. of moles of FeS = mass/molar mass</em> = (90.0 g)/(87.91 g/mol) = <em>1.024 mol.</em>

<u><em>∵ Fe reacts with S with (1: 1) molar ratio.</em></u>

∴ The no. of moles of S needed to react with Fe is 1.074 mol.

<em>∴ The no. of grams of S needed = no. of moles x molar mass </em>= (1.074 mol)(32.065 g/mol) = <em>34.44 g.</em>

If you know the mass of Earth, what other single value would you need to know to calculate Earth's average density?
Dennis_Churaev [7]

Answer:

Volume

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.  In order to find the density of earth when mass is given we have to calculate its volume. The volume of earth is calculated by using the volume formula for sphere. i.e 4/3 π r³. we also require radius to find the volume and we know that

Diameter = 2 × radius

The diameter of earth equator is 12756.75 Km. So we calculate the radius by dividing the diameter by 2. Then by putting the value of radius in 4/3 π r³ we will get the volume and then we can calculate the density of earth.

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

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.
