Question

calculate the mass of 3/8 mole of O2​

Answer 1

Most elemental gases, i.e. at least the ones with any chemistry … are BINUCLEAR, i.e. dihydrogen, dinitrogen, dihalogen, and DIOXYGEN, O2O2… And thus the mass of 3∙mol3•mol of dioxygen gas is 3∙mol×32∙g∙mol−1=96∙g3•mol×32•g•mol−1=96•g….

Answer 2

Answer:

we know that no.of moles =given mass / molecular mass

so Mass =12 au
