Question

2 sur 32 vous avez 98 g d’acide sulfurique (h₂so₄). calculez le nombre de moles d’acide sulfurique. 2 points a 1,5 mol c 0,1 mol e 0,75 mol b 0,5 mol d 1 mol

Explanation:

Step1: Calculate molar mass of \(H_2SO_4\)

Molar mass of \(H = 1\ g/mol\), \(S = 32\ g/mol\), \(O = 16\ g/mol\).
Molar mass \(M = 2\times1 + 32 + 4\times16 = 98\ g/mol\).

Step2: Use moles formula \(n=\frac{m}{M}\)

Given \(m = 98\ g\), \(M = 98\ g/mol\).
\(n=\frac{98\ g}{98\ g/mol}=1\ mol\).

Answer:

D. 1 mol
