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.
From early on in your pregnancy, your baby is more like a newborn than you might think. He sleeps, moves around, listens to sounds, and has thoughts and memories. Here's how: Just like newborns, fetuses spend most of their time sleeping. At 32 weeks, your baby sleeps 90 to 95 percent of the day. Some of these hours are spent in deep sleep, some in REM sleep, and some in an indeterminate state -- a result of his immature brain. During REM sleep, his eyes move back and forth just like an adult's eyes.
