The volume in liters occupied by 22.6 g of I₂ gas at STP is 1.99 L (answer A)

calculation

Step: find the moles of I₂

moles= mass÷ molar mass

from periodic table the molar mass of I₂ is 253.8 g/mol

moles = 22.6 g÷253.8 g/mol =0.089 moles

Step 2:find the volume of I₂ at STP

At STP 1 moles =22.4 L

0.089 moles= ? L

by cross multiplication

={ (0.089 moles x 22.4 L) /1 mole} = 1.99 L

Lead has a density of 11.4 g/cm^3. What is the density in kilograms per cubic meter?

Vikentia [17]

The density in kg/m³ = 1.14 x 10⁴

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³ or m³

A density of Lead : ρ = 11.4 g/cm³

the density in kg/m³ :

$\tt 11.4~\dfrac{g}{cm^3}\times \dfrac{kg}{10^3~g}\times \dfrac{cm^3}{10^{-6}~m^3}=\boxed{\bold{1.14\times 10^4~\dfrac{kg}{m^3}}}$
