If the total amount of the sample is 230g and they give each component of the sample, we add the given amount of grams of each element and subtract the given from 230g.


That means the rest of oxygen is 35.2g
This is Percent Composition.
The formula to find the percent composition of an element inside a compound is

Now we implement the variables into the formula to find the percent composition oxygen.
The answer is <span>
15.30% = O</span>
Is it because the bonds between hydrogen molecules for easier than bonds between chlorine molecules?
When determining slope, data points do not usually fall within a straight line, so you need to draw a TREND line, with as many points above and below the line as possible.
Trend line is also called line of best fit. Trend line refers to a line that is drawn through plotted data points, which best expresses the association between the points; that is, it shows the trend in the plotted points. The line is usually used to visually show the relationship between points, which may not be obvious from the data table
