What volume will 50.2 grams of co2 (g) occupy at stp?

Which is mostly likely why many scientists reject the cold fusion theory

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?
