Question

How many gram molecules of H2SO4 are present in 4.6g of the acid?​

Answer 1

Answer:

The number of sulfuric acid molecules in 4.9 g are 3.011\times 10^{22} molecules3.011×10

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 molMoles=frac4.9g98g/mol=0.05mol

Number of molecules ;

0.05 moles \times 6.022\times 10^{23}mol^{-1}=3.011\times 10^{22} molecules0.05moles×6.022×10
