Question

how many grams of h are present in 1.247725 mol h?
? g h
do not round! include lots of digits in your answer since this is part of a larger calculation.

Explanation:

Step1: Recall molar mass of H

The molar mass of hydrogen (H) is approximately \(1.00794\space g/mol\).

Step2: Use moles to grams conversion formula

The formula to convert moles to grams is \(mass = moles\times molar\space mass\).
Given moles of H \(n = 1.247725\space mol\) and molar mass \(M = 1.00794\space g/mol\).
So, \(mass = 1.247725\space mol\times1.00794\space g/mol\)
Calculating this: \(1.247725\times1.00794 = 1.2576333865\)

Answer:

\(1.2576333865\)
