Calculate the number of molecules in 0.5 mol of sulfur dioxide, SO2. Describe what is meant by a mole of sodium atoms. I need answers ASAP

We know, 1 mole of any element/compound contains 6.022 × 10²³ atoms/molecules .

Now, we have to calculate the number of molecules in 0.5 mole of sulfur dioxide, SO₂.

So, number of molecules of SO₂ in 0.5 mole is :

Therefore, number of molecules in 0.5 mole of SO₂ is 3.011 × 10²³.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
