Question

what is the mass of 1.5 mol of nacl?
molar mass nacl = 58.44 g/mol
1.5 mol nacl = ? g nacl

Explanation:

Step1: Recall the formula

The formula for calculating mass ($m$) from moles ($n$) and molar mass ($M$) is $m = n\times M$.

Step2: Substitute the values

Given $n = 1.5\space mol$ and $M=58.44\space g/mol$.
Substitute into the formula: $m=1.5\times58.44$.

Step3: Calculate the result

$1.5\times58.44 = 87.66$.

Answer:

$87.66\space g$
