density= mass/volume
we need the volume of the metal to find the density, in which case the answer would be 64.2/volume=density
There are 1.2 moles of KBr found in 3 Liters of 0.4 M solution.
<h3>HOW TO CALCULATE NUMBER OF MOLES?</h3>
The number of moles of a substance can be calculated by multiplying the molarity by the volume.
No. of moles = Molarity × volume
According to this question, 3L of a KBr solution are contained in a 0.4M.
no. of moles = 3L × 0.4M = 1.2moles
Therefore, there are 1.2 moles of KBr found in 3 Liters of 0.4 M solution.

The reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a secondary electrophile will decrease.
SN1 exhibits substitution, nucleophilicity, and monomolecular reaction, and is expressed by the expression rate = k [R-LG]. This means that the rate-determining step of the mechanism depends on the degradation of a single molecular species. Multi-step reactions include intermediates and multiple transition states (TS).
The SN1 reaction is a nucleophilic substitution reaction in which the nucleophile replaces the leaving group (similar to SN2). However, the SN1 reaction is a single molecule. The rate of this reaction depends on the concentration of only one reactant.
