The 4 in 4H2 stand for "4" molecules in that equation, unless specified as being moles.

The answer depends on what you mean by "7 Th's".

If you mean 2/3 then 2/3 of 18 = 12 and 18/2 = 9

The mean is 38.

It is calculated the same way as if there were an odd number of numbers:mean = sum of all the numbers ÷ how many numbers there areThe median however is calculated slightly differently. After the numbers have been sorted into order, then:If there is an odd number of numbersThe median is the middle one which is the ((number_of_numbers + 1)÷2)th one. eg if there are 15 numbers this is the ((15+1)÷2)th = 8th number.If there is an even number of numbersThe median is given by the mean of the middle two numbers. eg if there are 20 numbers, then the median is the mean of the (20÷2)th = 10th and the (20÷2+1)th = 11th numbers, ie the median is (10th number + 11th number)÷2
