Question

For 78.4g of H2SO4 calculate moles

Answer 1

Answer:

No of moles = given mass / molecular mass

                     = 78.4 / 98

                      = 0.8 moles of H2SO4

                                 

Answer 2

Number of moles of 0.8.

Given - Mass

Find - Number of moles

Solution - Number of moles is calculated by the formula = mass/molar mass

Molar mass of H2SO4 = 98 g/mol

Number of moles = $\frac{78.4}{98}$

Performing division

Number of moles = 0.8

Hence, the number of moles is 0.8.
