Question

question 8 (1 point)
the gram molecular mass (in g/mol) of h₂so₄ is
98
49
48
7

Explanation:

Step1: Calculate the molar mass of hydrogen (H)

The molar mass of \(H\) is \(1\space g/mol\). There are \(2\) \(H\) atoms in \(H_2SO_4\), so the contribution of \(H\) is \(2\times1 = 2\space g/mol\)

Step2: Calculate the molar mass of sulfur (S)

The molar mass of \(S\) is \(32\space g/mol\). There is \(1\) \(S\) atom in \(H_2SO_4\), so the contribution of \(S\) is \(32\times1=32\space g/mol\)

Step3: Calculate the molar mass of oxygen (O)

The molar mass of \(O\) is \(16\space g/mol\). There are \(4\) \(O\) atoms in \(H_2SO_4\), so the contribution of \(O\) is \(4\times16 = 64\space g/mol\)

Step4: Sum up the contributions

$$M = 2 + 32+64=98\space g/mol$$

Answer:

\(98\space g/mol\) (the first option)
