Question

calculate the number of 52g of he​

Answer 1

Answer:

to find the no. of molecules in something when the weight is given the fomula is given wt divided by gram atomic wt or gram molecular weight. and then we get mole .

we have 52g of he whose atomic wt is 4 .

so 52/4 which is 13 mole .

Now to convert mole to no. of particles or molecules we will multiply it by 6.023 x 10^23

so 13 x 6.023 x 10^23 is 78.299 x 10^23
