At STP one gram mole of an IDEAL gaseous substance occupies 22.7 liters. Hence the if an element is in a gaseous state with volume V liters the number of moles is =V/22.7 approximately. Dimension less this number indicates the chemical mass of any reactant to calculate yields.
Follow these recommendations for a safe sleep environment for your little one: 1  Always place your baby on his or her back to sleep, not on the stomach or side. 2  Use a firm sleep surface. 3  Do not put anything else in the crib or bassinet. 4  Avoid overheating. 5  Keep your baby away from smokers. 6  Put your baby to sleep with a pacifier. But if your baby rejects the pacifier, don't force it. If the pacifier falls out during sleep, you don't have to replace it.
