Answer:
93.5 moles N₂
Explanation:
To find the moles, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = constant (0.0821 atm*L/mol*K)
-----> T = temperature (K)
You can plug the given values into the equation and simplify to find moles. The final answer should have 3 sig figs to match the lowest number of sig figs among the given values.
P = 95.0 atm R = 0.0821 atm*L/mol*K
V = 224 L T = 2773 K
n = ?
PV = nRT
(95.0 atm)(224 L) = n(0.0821 atm*L/mol*K)(2773 K)
21280 = n(227.6633)
93.5 = n
Answer:
The seven SI base units, which are comprised of:
Length - meter (m)
Time - second (s)
Amount of substance - mole (mole)
Electric current - ampere (A)
Temperature - kelvin (K)
Luminous intensity - candela (cd)
Mass - kilogram (kg)
Explanation:
Answer:
Igneous rocks must go through the sedimentary process to change into metamorphic rocks. Igneous rocks are chemically changed into metamorphic rocks because of high temperature and pressure. Metamorphic rocks are formed from melting igneous rocks. Metamorphic rocks and igneous rocks do not follow a rock cycle.

Balanced chemical equation for the hydrogenation of glyceryl trilinolenate:
C₅₇H₉₂O₆ + 9H₂ → C₅₇H₁₁₀O₆.
Linolenic acid (octadecatrienoic acids ) is a type of fatty acid. It has 18 carbon atoms chain and three double bonds. So trilinolenate has nine double bonds.
Trilinolenate is the form of triglyceride esters of linolenic acid.
Hydrogenation is addition of hydrogen atoms at both sides of a double bond.
Answer:
Original volume=3L
Explanation:
Assuming the gas in the ballon is ideal and the temperature does not vary with height we have the gas law as
PV=nRT
Here RHS is constant in both the conditions which means
PV=constant
Given P1=1 atm V1=V P2=0.75atm V2=4L
P1V1=P2V2

V=3L
The initial volume of the gas is 3L
