A class 10 result on an algebra test might mean that 80 percent of the class passed the test. This might also mean that 20 percent of sophomores passed the test with at least a B.
the easiest way of changing a number into a percent is when it is a fraction for example, 2/25 --> 8% because a percent has a denomenator of 100, so you multiply 25 by 4 and do the same with 2 to get 8/100 which is 8% Now if its a decimal, then you can change it to a fraction and get your answer. for example, 0.2 --> 2/10 --> 20% 0.02 --> 2/100 --> 2% Hope you got it! :)
At first glance the question seems not to have enough information. Thinking about it, there is enough information for some general observations. 78 percent is quite a large proportion of a population. For example, if a US president won with 78 percent of the popular vote, that would be a breathtaking landslide by anyone's reckoning. If 78 percent of a random population were male, or were female, that would be seriously outlandish and an indication that something is seriously wrong. If 78 percent of a sample of 500 people had recorded IQ's of 100 or better given the generally understood mean and s.d. of IQ, then that would be very strong evidence that the population was not chosen randomly. Apart from this general kind of observation, 78 percent is virtually meaningless unless you give the number out of which you are isolating the 78 percent. For example, 78 percent of a sample of 100 people would be 78 people. 78 percent of the world's population would be considerably larger than that.

The mass percent composition of an element in a compound is the percentage of the total mass of the compound that comes from that specific element. It is calculated by dividing the mass of the element by the total mass of the compound and multiplying by 100.
Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.
gold at 13%
Take 1.45 wt% oxide as an example. To remove the oxide component first you must work out the Ti component: 1.45 wt% oxide x 0.6 = Ti (wt%) because Ti in TiO2 makes up 60% its formula mass: 47.87 / 79.87 = ~0.6 Ti Thus 1.45wt% TiO2 = 0.87 wt% Ti
it tells you how much of the molecule the element is
it tells you how much of the molecule the element is
Oxygen
To calculate the percent by mass of an element in a compound, you divide the mass of the element by the total mass of the compound and then multiply by 100. This gives you the percentage of the compound's mass that is made up of that specific element.
anything thats a non example of a percent is the answer
Percent abundance is calculated by determining the proportion of a specific isotope of an element relative to the total amount of all isotopes of that element. To find it, divide the number of atoms of the isotope by the total number of atoms of all isotopes, then multiply by 100 to convert it to a percentage. For example, if an element has two isotopes, with 75 atoms of isotope A and 25 atoms of isotope B, the percent abundance of isotope A would be (75 / (75 + 25)) × 100 = 75%.
