if i have 2.4 moles of gas held at a temperature of 97 c and in a container with a volume of 45 L , what is the pressure of the

choli [55]

Answer:

1.62 L

Explanation:

T= 97+273.15= 370.15

R= 0.08206 atm/mol⋅K

V= 45 L

n= 2.4 mol

P= (n⋅R⋅T)/V

= (2.4 x 0.08206 x 370.15)/(45) = 1.61997 = 1.62

A lead sphere has a mass of 1.20 x 104 g, and its volume is 1.05 x 103 cm^3. Calculate the density of lead.

Hatshy [7]

Answer: The density of lead will be $11.42g/cm^3$

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of lead= $1.20\times 10^4g$

Volume of lead = $1.05\times 10^3cm^3$

Putting in the values we get:

$Density=\frac{1.20\times 10^4}{1.05\times 10^3}=11.42g/cm^3$

Thus density of lead will be $11.42g/cm^3$
