When carbon dioxide is at 1 atmosphere and 273k How many liters make up 28.45g of carbon dioxide ?molar mass of co2 =44g/mol

What is the mass of 2.00 l of an intravenous glucose solution with a density of 1.15 g/ml?

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m

Is this correct if not can u correct me
