Not exactly. 1st you need to convert that volume to liters, otherwise that R value is useless (1 dm^3=1L),and (10dm=1m). This is because the units of R are (atmL/[molK]) Then when you find n, note that it’s units are in moles, so you multiply by 55.85 not divide, because the units are 55.85grams/mole. Same thing for H2SO4 except you divide by .99 in the end to account for the 99%
