Answer 1

Answer:

calculate no. of moles in 320 gm of O2 gas---- 10 moles

Answer 2

${\dag} \: {\underline{\boxed{\sf{\purple{ Answer }}}}}$

The atomic mass of oxygen molecule = 32 g

Given mass = 320 g

The moles of oxygen molecules = Given mass / Molar mass

                                                    = 320 g / 32 g 

                                                    = 10
