Question

how many atoms are present in 50g of so2​

Answer 1

Explanation:

The molecular formula of CaCO3 is 40+12+(16)3= 100

Hence, we have 50/100= 0.5mol of CaCO3.

From the formula, we can see that in 1 mol of CaCO3, 3 mol of oxygen atoms are present.

Hence, in 0.5 mol, we have 1.5 mol of oxygen atoms.

1 mol=6.022*10^23 particle, which, by math, gives us 9.011*10^23 atoms of oxygen in 50g of CaCO3.

Answer 2

Answer:

many atoms are there in so2?

The sample of SO2 contains 0.253 mol x (6.022 x 1023 molecules / 1 mol) = 1.52 x 1023 molecules of SO2. 4
