Question

calculate the

a) No of mol

b) No of molecules

c) No of atoms

d) mass of H2SO4

✴ PRESENT IN 21 GRAM ATOM OF H2SO4.

Answer 1

ANSWERS :-

1 mole of H2SO4 = 6.022 * 10²³ molecules = 98 gram = 1gram–atom

= 7 * 6.023 *10²³atoms = 7 gram atom

we calculate first of all atom ,

7 gram – atom contain = 7*6.023*10²³ atom

1 gram – atom contain = 7*6.023*10²³/7 atom

21 gram – atom contain = 7*6.023*10²³*21/7 atom

question c ) answer = 21 * 6.023 *10²³ atom

Now ,

we calculate no of mole = 21 * 6.023 * 10²³/7 * 6.023 *10²³

question A answer = 3 mole

Now ,

question B answer =
No of molecules = 3 * 6.023 * 10²³

Now,

QUESTION D ANSWER

mass of H2SO4 = 98 * 3

= 294 gram
