Question

use the following balanced equation to answer the questions: 4k + 2s → 2k₂s. there are 2 moles of s present. the molar mass of sulfur is 32.07 g/mol. what mass of sulfur is present?

Explanation:

Step1: Recall mass - mole relationship formula

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

Step2: Substitute given values

We know $n = 2$ mol (moles of S) and $M=32.07$ g/mol (molar mass of S). So $m=2\ mol\times32.07\ g/mol$.

Step3: Calculate the mass

$m = 64.14$ g.

Answer:

64.14 g
