Question

a sample of hno3 contains 1.01 g of h, 14.01 g of n, and 48.00 g of o. what is the percent composition of n? ?% n

Explanation:

Step1: Calculate the total mass of the sample

The total mass \(m_{total}\) is the sum of the masses of \(H\), \(N\), and \(O\).
\(m_{total}=1.01 + 14.01+48.00\)
\(m_{total}=63.02\space g\)

Step2: Calculate the percent composition of \(N\)

The formula for percent composition is \(\text{Percent Composition}=\frac{\text{Mass of Component}}{\text{Total Mass}}\times100\%\)
For \(N\), \(\text{Percent Composition of }N=\frac{14.01}{63.02}\times 100\%\)
\(\text{Percent Composition of }N\approx22.23\%\)

Answer:

\(22.23\)
