Question

can you convert these gram values into moles? it seems like there is relatively 36.84 g of nitrogen and 63.16 grams of oxygen. to find the empirical formula, youll need to know the whole number mole ratio between these two elements. how can you convert these mass values (in grams) into mols? n = mol 36.8g o = mol 63.2g

Explanation:

Step1: Calculate moles of nitrogen

Use the formula \(n=\frac{m}{M}\), where \(m\) is mass and \(M\) is molar mass. Molar mass of \(N\) is \(14\space g/mol\).
\(n_{N}=\frac{36.84\space g}{14\space g/mol}\)

Step2: Calculate moles of oxygen

Molar mass of \(O\) is \(16\space g/mol\).
\(n_{O}=\frac{63.16\space g}{16\space g/mol}\)

Answer:

\(N = 2.63\space mol\)
\(O = 3.95\space mol\)
