Answer:
313 g
Explanation:
The formula for density is [tex]D = Mass / volume[/tex] in Litters (L).
Given that the density is 1.25[tex]g/mL[/tex] and that the solution is 2.5[tex]L[/tex]
You first have to plug in what is given into the density formula like so [tex]1.25 g/mL = Mass/2.5L[/tex] but note that the answer is in milliliters not Litters so you have to convert [tex]2.5 L[/tex] in milliliters like so [tex]2.5 L * 1000 mL/ 1 L[/tex] or [tex]2.5L * 10^3/ 1L[/tex] Which equals 2,500mL next you do simple math like so[tex]1.25g/mL = Mass /2,500 mL[/tex]
[tex]1.25 g/mL * 2,500mL = m[/tex] or the Mass
[tex]3,125 g = m[/tex] but that not the answer because you need to round to 3 significant figure so your actual answer is [tex]313g[/tex]
