Serga [27]

Answer:

<h2>8</h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

From the question we have

ph  =  -  log(1 \times  {10}^{ - 8}  )  \\  = 8

We have the final answer as

The molecular weight of H2SO4 is:<br>49.078 g/mole<br>98.086 g/mole<br>194 296 armoe​
a_sh-v [17]

Answer:

The answer to your question is:   98 gr / mole

Explanation:

Molecular weight and molecular mass are synonyms and they referred to sum of the the molecular masses of the elements that form part of a compound. Their units are grams/ mole

In your example we need to sum the molecular mass of the components of sulphuric acid.

Like this:

Hydrogen(H) = 1.008 x 2

Sulphur (S)     = 32 x 1 = 32

Oxygen =          16 x 4 = 64

Total     =                       98 gr / mole
