Explanation:
This question is incomplete, the complete question;
A reaction between liquid reactants takes place at 16°C in a sealed, evacuated vessel with a measured volume of 10.0 L . Measurements show that the reaction produced 37.g of dinitrogen monoxide gas.
Calculate the pressure of dinitrogen monoxide gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits.
Answer:
Explanation:
Given that;
Volume = 10.0 L
Temperature T = 16°C = ( 16 + 273) = 289 K
we know that molar mass of N₂O = 44 g/mol
number number of moles n will be: weight/molar mass = 37/44 = 0.8409 moles
Universal Gas constant R = 0.0821 atm.mol⁻¹.k⁻¹
pressure p = ?
from the ideal gas law
PV = nRT
P = nRT / n
so we substitute
P = (0.8409 mole × 0.0821 atm.mol⁻¹.k⁻¹ × 289 K) / 10.0 l
P = 19.95195 / 10.0
P = 1.9952 atm
There are several things that can help scientists evaluate which category something belongs to. The similarity in features is one of them. If two skulls looked alike, they were probably species of the same evolutionary category. For example say humans and monkeys rather than humans and dogs.
Similarly fossils have helped scientists categorise species. Study of the chromosomes (in cases with available chromosomes) can help scientists figure out a lot about the subjects and categorise them.
