the molar mass of nickel, ni, is 58.69 g/mol. how many grams of nickel are in 1.57 mol ni? ? g ni

Explanation:

Step1: Recall the mass - mole relationship formula

The formula is $m = n\times M$, where $m$ is mass, $n$ is the amount of substance in moles, and $M$ is molar mass.

Step2: Substitute the given values

Given $n = 1.57\ mol$ and $M=58.69\ g/mol$. Then $m=1.57\ mol\times58.69\ g/mol$.

Step3: Calculate the mass

$m = 1.57\times58.69\ g=92.1433\ g$.

Answer:

$92.14\ g$
