What is the number of molecules in each of 32g `O_(2) and 44g CO_(2)`?

What is the number of molecules in 11.2 litre of O_(2) at STP?

Give the number of molecules is 2 g hydrogen.

8 g of O_2 has the same number of molecules are :

8g of O_(2) has the same number of molecules as-

Compare the wavelengths of a molecule of each O_(2) and CO_(2) , travelling with the same velocity.

Find out the ratio of the volumes occupied .by 32g O_2 and 44g CO_2 gases at 27^@C temperature and 700 mmHg pressure. ( C = 12, Q = 16)

What is the volume of 11g of CO_(2) at STP?

Calculate the following Number of atoms in 32.0 g Br_2

Calculate the total number of (a) molecule, (b) oxygen atoms and (c ) neutrons in 4.4 g of CO_2 (g).

Calculate the number of O-atoms in 88g of CO_(2) . Also calculate the mass of CO which will contain the same number of O-atoms.
