Answer:

Mass = 6.79 g

Explanation:

Molarity = 0.155

Volume = 0.75L

Mass = ?

The relationship between these quantities is given as;

Molarity = Number of moles / Volume

Number of moles = Volume * Molarity

Number of moles = 0.75 * 0.155 = 0.11625 moles

Number of moles = Mass / Molar mass

Mass = Molar mass * Number of moles

Mass = 58.44277 g/mol * 0.11625 mol

Mass = 6.79 g

gavmur [86]

Answer:

The rate of reaction of a zero-order reaction  is 0.0020 mol/L.

Explanation:

The rate expression of the zero order kinetic are :

R=k[A]^o

[A]= initial concentration of reactant

k = rate constant

R = rate of reaction

We have :

Rate constant of the reaction , k = 0.0020 mol/L s

R=0.0020 mol/L s\times 1

R = 0.0020 mol/L s

The rate of reaction of a zero-order reaction  is 0.0020 mol/L.
