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.
Note: These recommendations are for healthy babies up to 1 year of age. A very small number of babies with certain medical conditions may need to be placed to sleep on their stomachs. Your babyâs doctor can tell you what is best for your baby. What you can do? Place your baby to sleep on his back for every sleep. Babies up to 1 year of age should always be placed on their backs to sleep during naps and at night. However, if your baby has rolled from his back to his side or stomach on his own, he can be left in that position if he is already able to roll from tummy to back and back to tummy. If your baby falls asleep in a car safety seat, stroller, swing, infant carrier, or infant sling he should be moved to a firm sleep surface as soon as possible. Place your baby to sleep on a firm sleep surface.
