Question

calculate the no of moles for 49g of h2so4​

Answer 1

Answer:

0.5 moles of H2SO4.

Step-by-step explanation:

No. of moles = Given mass / Molecular mass

As we know, the molecular mass of H2SO4 is 98g

No. of  moles = 49/98

                      = 1/2

Therefore, there are 0.5 moles in 49g of H2SO4.

This is your answer.

Hope it helps!

Answer 2

Given :

• 49g of H2SO4

To find :

• Number of moles for 49g of H2SO4

Formula used :

$\sf n = \dfrac{mass }{molar \: mass}$

where n is number of moles

Solution :

Mass of H2SO4 = 49 grams

Molar mass of H2SO4 =( 2×1)+ 32+ (16×4)

=> 2+ 32+ 64

=> 2+ 32+ (16×4)

=> 98 u

Now we will find number of moles :-

$\sf \implies n = \dfrac{49 }{98}$

$\sf \implies n = \dfrac{1 }{2}$

$\sf \implies n = 0.5 \: moles$

Answer :

• Number of moles for 49g of H2SO4 = 0.5 moles
