Question

3.92 g of sulphuric acid calculate the no of moles​

Answer 1

Answer:

0.0399

Explanation:

no. of moles = given mass/molar mass

so, no. of moles = 3.92/98.07

=0.0399

Answer 2

Answer:

No. of moles = 0.047 per mol.

Explanation:

Given mass of sulphuric acid = 3.92 kg

so,, molecular mass of H2 SO 4 = 1×2+32+ 4×16= 34+48 = 82 g/molecular

Now,,

No. of moles = given mass/ molecular mass = 3.92/ 82

= 0.047 ... per mol.
