How many molecules are in 49.0 g of H2SO4? Answer in units of molec.
Leokris [45]

Answer:

= 3.01× 10^{23} molecules.

Explanation:

1 mole of H_{2}SO_{4} - 98g

? moles of H_{2}SO_{4} - 49g

= 49 ÷ 98 = 0.5 moles of O2 in 49g.

But 1 mole of any substance = 6.023 × 10^{23} molecules

∴ 0.5 moles = 0.5 × 6.023 × 10^{23} molecules

= 3.01× 10^{23} molecules.
