Ribose is an important sugar that is found in dna and rna. ribose has a molar mass of 150g/mol, and a percent composition of 40.0%c,6.67%h, and 53.5%o. what is the molecular formula for ribose

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
