what is the mass of 1.84 mol nacl? give your answer to the correct number of significant figures. (molar…

Answer:

108

Explanation:

Step1: Recall mass - mole formula

$m = n\times M$ where $m$ is mass, $n$ is number of moles, and $M$ is molar mass.

Step2: Substitute given values

$n = 1.84\ mol$, $M=58.44\ g/mol$ $m=1.84\ mol\times58.44\ g/mol$

Step3: Calculate the mass

$m = 1.84\times58.44=107.53\ g$

Step4: Round to correct significant figures

Since 1.84 has 3 significant figures, the answer is rounded to 3 significant figures, so $m = 108\ g$
