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.
Newborn babies sleep a lot. Expect your baby to be asleep for up to 18 hours over the course of 24 hours in his first few weeks. But he won't sleep for more than three hours or four hours at a time, day or night (Davis et al 2004) .ll this should help your baby to start to understand that night-time is for sleeping (Sleep 2003) . Give him a chance to fall asleep on his own. When your baby's between six weeks and eight weeks old, you can teach him how to fall asleep on his own. Put him down when he's sleepy, but still awake.
