Question

how many gram molecules are present in 4.9 g of H2SO4?

Answer 1

Answer:

The number of sulfuric acid molecules in 4.9 g are $3.011\times 10^{22} molecules$

Explanation:

Mass of sulfuric acid = 4.9 g

Molar mass sulfuric acid = 98 g/mol

$Moles=frac{4.9 g}{98 g/mol}=0.05 mol$

Number of molecules ;

$0.05 moles \times 6.022\times 10^{23}mol^{-1}=3.011\times 10^{22} molecules$

The number of sulfuric acid molecules in 4.9 g are $3.011\times 10^{22} molecules$

Answer 2
