Question

Calculate the number of molecules present in 2.25 mol H2SO4. 2.25 x 1023 molecules 1.35 x 1024 molecules 3.53 x 1023 molecules

Answer 1

Answer:1.35 x 10^24

Step-by-step explanation:

No. of molecules= mole x avogadro's constant

2.25 x 6.02 x 10^23

=1.35 x 10^23

Answer 2

Answer: The number of molecules in given amount of sulfuric acid is
`1.35* 10^(24)`

Step-by-step explanation:

According to the mole concept:

1 mole of a compound contains
`6.022* 10^(23)` number of molecules.

We are given:

Moles of sulfuric acid = 2.25 mole

So, the number of molecules that will be present in 2.25 moles of sulfuric acid will be
`2.25* 6.022* 10^(23)=1.35* 10^(24)` number of atoms.

Hence, the number of molecules in given amount of sulfuric acid is
`1.35* 10^(24)`
