We assume it as an ideal gas therefore we can use the
ideal gas equation to solve the problem. The ideal gas equation is expressed as
PV = nRT. We are given the volume, temperature and pressure. Therefore, we can solve for the amount of the gas in moles.
<span>
n = PV / RT
n = </span>1.00(3L) / (<span>0.08206 atm L/mol K ) 273 K
n = 0.1339 mol

Answer:
This question is asking whether the statement is TRUE OR FALSE
THE ANSWER IS TRUE
Explanation:
A concept, as rightly defined, is the general idea of an entity, which can include objects, events, animals, or people based on common features, traits, or characteristics. Hence, the CONCEPT of something refers to a a generalized idea about that particular thing.
A concept in other words is our thought about something i.e. how we conceive or think that thing to be. Concept is a phenomenon of the "MIND" since it is abstract and cannot be seen. Based on this, the definition given in the question is TRUE.
The answer is B. A guitar generally produces sound waves that propagate when the strings are strummed. The strings are displaced through the vibrations caused by contact of the hand and the guitar. You will also notice the vibrations by looking closely to the string. Wave particles continuously collide with each other to make a sustaining or prolonging sound.
Answer:
1.750 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 7.14 mL
M₂ = 0.250 M
V₂ = 50 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 7.14 mL = 0.250 M * 50mL
M₁ = 1.750 M
Hence, the molarity of the hydrochloric acid = 1.750 M
