How many moles are in 2.3x1024 g of Ag?<br> Plz help!!
ziro4ka [17]

Answer:

              2.13 × 10²² moles

Explanation:

Relation between Mole and Mass is,

                             Mole = Mass / M.Mass

Putting values,

                             Mole = 2.3 × 10²⁴ g / 107.87 g/mol

                             Mole = 2.13 × 10²² moles

An unknown gas is found to diffuse through a porous membrane 4.11 times more slowly than h2 what is the molecular weight of the
kirill [66]
To answer this question, you need to know <span>Graham's Law of Effusion/Diffusion formula. In this formula, the rate of diffusion/effusion would be influenced by the mass. As the molecule has bigger mass, the rate should be slower because it will be harder to pass the membrane. The calculation should be:</span>
<span>Rate 1 / Rate 2 = √[M2/M1] 
</span>4.11/1= √[M2/2] 
M2=33.78 g/mol
