Asample of gas with a mass of 8.40 g occupies a volume of 4.50 l at 298 k and 1.10 atm. what is the molar mass of the gas?

41.5225 g/mol

Explanation:

Given that:

Pressure = 1.10 atm

Temperature = 298 K

Volume = 4.50 L

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

1.10 atm × 4.50 L = n × 0.0821 L.atm/K.mol × 298 K  

⇒n = 0.2023 moles

Given that : Amount = 8.40 g

Molar mass = ?

The formula for the calculation of moles is shown below:

Thus,

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
