Answer 1

Answer:

1.Usually, density will have units of $\frac{g}{mL}$

when dealing with a liquid or units of  $\frac{g}{cm^3}$ when dealing with a solid.

The mass has units of grams, g.

The volume will have units of $mL$ or $Cm^{3}$

We are given the mass and the volume, both of which have good units, so all we have to do is plug the given values into the equation:

Density = $\frac{40.5g}{15.0mL}$

Thus, the block of aluminum has a density of 2.70 g/mL.

2. d = 13.6 g/mL

------------------------------------------------------------------------------------

3. g = (0.789 g/mL) (200.0 mL) = 158 g

------------------------------------------------------------------------------------

4. d = 1896 g / 212.52 cm3 = 8.9 g/cm3

------------------------------------------------------------------------------------

5.d = 1.84 g/mL

Answer 2

#1

• Volume=15mL
• Mass=40.5g

$\\ \sf\longmapsto Density=\dfrac{Mass}{Volume}$

$\\ \sf\longmapsto Density=\dfrac{40.5}{15}$

$\\ \sf\longmapsto Density=2.7g/mL$

#2

• Mass=306g
• Volume=22.5mL

$\\ \sf\longmapsto Density=\dfrac{306}{22.5}$

$\\ \sf\longmapsto Density=13.6g/mL$

#3

• Density=0.789g/mL
• Volume=200mL

$\\ \sf\longmapsto Mass=Density(Volume)$

$\\ \sf\longmapsto Mass=0.789(200)$

$\\ \sf\longmapsto Mass=157.8g$

#4

$\\ \sf\longmapsto V=LBH$

$\\ \sf\longmapsto V=8.4(5.5)(4.6)$

$\\ \sf\longmapsto V=212.5cm^3$

• Mass=1896g

$\\ \sf\longmapsto Density=\dfrac{1896}{212.5}$

$\\ \sf\longmapsto Density=8.92g/cm^3$

#5

• Mass=65.14g
• Volume=35.4mL

$\\ \sf\longmapsto Density=\dfrac{65.14}{35.4}$

$\\ \sf\longmapsto Density=1.8g/mL$
