nm3/hr to kg/hr

We are measuring volumetric flow of SO3(10%) + Air(90%) in Nm3/hr.
Please calculate 1600 Nm3/hr is in kg/hr.

What sort of sulphite? - It doesn't exist as a gas on its own, it has to be with something else, which will change the weight. SO2 is a gas, could it be a typo in your text?

Depends on the molecular weight of the gas (which can be an average molecular weight for a mixture). The molecular weight is also the molar mass in grams per mole.

At "normal" conditions, an ideal gas occupies 22.414 L/mol,
so divide flow in Nm³/h by 0.022414 m³/mol to get moles, then multiply by molecular weight to get grams per hour, divide by 1000 for kilograms per hour.

See post 4 on molar volume and molar mass.
255 Nm³/h = 11.4 kmol/h = 22.8 kg/h for H2
