Question

please answer step by step
both​

Answer 1

Answer:

Since 3.18 moles is the quantity of 12 H atoms

X moles will be quantity of 4 0xygen atoms

Using rules of proportion

3.18*4=x*12

X=1.06 moles

Note that when question states

Eg 2moles of AgNO3

It means

2moles of Ag

2 moles of N

2 moles of 03

The last statement means

2 moles of three O bonded together

So in effect

2*3 moles of O

Hence above solution

Second answer

Find out moles as moles are universally constant

8g of H2 means 4moles

64 g of SO2 means 1 mole

44 g of CO2 means 1mole

48 g of O3 means 1 mole

Comparing moles H2 has highest molecules

As 1 mole of any compound means

It has 6.023*10^23 molecules
