What is biodiversity in chemistry?

Dahasolnce [82]

Answer:Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richest in the tropics.

An ideal gas has a temperature of 25 oC, a pressure of 1.7 atm, and volume of 345 mL, how many moles of gas are present in the c

Sholpan [36]

Answer: There are 0.024 moles of gas are present in the container.

Explanation:

Given: Temperature = $25^{o}C$ = (25 + 273) K = 298 K

Pressure = 1.7 atm

Volume = 345 mL (1 mL = 0.001 L) = 0.345 L

Formula used is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T= temperature

Substitute the values into above formula as follows.

$PV = nRT\\1.7 atm \times 0.345 L = n \times 0.0821 L atm/mol K \times 298 K\\n = \frac{1.7 atm \times 0.345 L}{0.0821 L atm/mol K \times 298 K}\\= \frac{0.5865}{24.4658} mol\\= 0.024 mol$

Thus, we can conclude that there are 0.024 moles of gas are present in the container.
