Moles=mass/molar mass of water. the molar mass of water is found to be 18g which is calculated adding the molar mass of hydrogen plus that of oxygen that is(2x 16)+(1 x2)=18g/mol
convert Kg to grams that is 1.8kg x 1000=1800g
moles is therefore 1800g /18g/mol=100 mol
The mouth
Amongst the most vital areas to protect are the neck, face and mouth. Though keeping a set of tiger whites will be most people’s primary concern the gum and mouth guards of today also help reduce the risk of concussions and tongue injuries resulting from impacts to the jaw. The most common mouth guards available are “boil and bite” types. These are heated in order to be moulded around the user’s teeth and then form a more resistant solid on cooling. Their main component is poly(ethylene-vinyl acetate) or PEVA, made from the polymerisation of ethene with vinyl acetate.
the synthesis of PEVA by radical polymerisation
