The basic substances are called elements
The mass percent of each compound is
- (NaBr*2H2O)=85.71 percent
- (MgBr2*6H2O)=14.29 percent
<h3>The mass percent equation is as follows.</h3>
The formula mass percent is the most effective way to express mass percent: mass percent = (mass of chemical x total mass of compound) times 100. Add 100 to the top value to get the value expressed as a percentage.
<h3>What percentage by mass does a solution have?</h3>
By multiply the grams of solute per gram of solution by 100, it is possible to get the mass percent of a solution.
The molar mass of each element and the mass of each element contained in a mole of the compound are both solved for in the Mass Percent formula.

The lowest amount of significant figures has to be what the answer is...
7.6cm is 2 sig figs where 13.48 is 4, so the answer can only really be as precise as the smallest one (7.6)
7.6 + 13.48 = 21.08cm
Put it into 2 sig figs makes it
=21 cm (2s.f) <— don’t forget to write 2 sig figs next to it because otherwise it is a false answer
