Answer:
783g
Explanation:
density = mass/volume
2.70mL/g = xg/290mL
2.70(290) = xg
x = 783g
CHECK:
783/290 = 2.7
Answer:
783 grams
Explanation:
The density formula is:
[tex]d=\frac{m}{v}[/tex]
Rearrange the formula for [tex]m[/tex], mass. Multiply both sides of the formula by [tex]v[/tex].
[tex]d*v=\frac{m}{v}*v[/tex]
[tex]d*v=m[/tex]
The mass can be found by multiplying the density and the volume.
Aluminum has a density of 2.70 grams per milliliter and the volume of this piece is 290 milliliters.
[tex]d= 2.7 g/mL\\v=290 mL[/tex]
Substitute the values into the formula.
[tex]m=d*v[/tex]
[tex]m=2.7 g/mL *290 mL[/tex]
Multiply. When multiplying, the milliliters, or "mL" will cancel each other out.
[tex]m= 2.7 g * 290[/tex]
[tex]m=783 g[/tex]
The mass of the aluminum is 783 grams.
