Given the following information:

Fish tank is: 15 inches high x .075 m wide x 30 cm long
Density of water of 1 g/cm3
1 cm3 is equal to 1 mL
D=M/V
Calculate the mass of the water, in grams, the Fish tank can hold.

You must show all conversions and work for full credit.

Step by Step Explanation

From the question,
the dimensions of the tank are;

L = 30 cm, way =0.075m and H = 15 cm

The density of water is given as
[tex]D = 1g {cm}^{ - 3} [/tex]

The unit of density given in the question means that the mass of the water is in grams and the volume should also be in
[tex] {cm}^{3} [/tex]

To find the volume of the water, we first convert the units of dimensions given in inches and metres to centimetres

[tex]1 inch = 2.54 cm[/tex]

This implies that ,

[tex]H=15 inches=15×2.54cm=38.1cm[/tex]

Also,

[tex]100cm=1m[/tex]

This implies that,
[tex]w= \frac{0.075}{100 } = 7.5 \times {10}^{ - 4} cm[/tex]

Now, the volume of water in the tank can hold, can be found from the relation;

[tex]V=L\times W\times H[/tex]

This implies that,

[tex]v = 30cm \times (7.5 \times {10}^{ - 4} )cm \times 38.1cm[/tex]

[tex]v = 0.857 {cm}^{3} \: to \: 3 \: d.p[/tex]

Finally, we can calculate the mass of the water from the relation given;

[tex]D=\frac{M}{V}[/tex]

This in implies that

[tex]1g {cm}^{ - 3} = \frac{m}{0.857 {cm}^{3} } [/tex]
[tex]m = 1g {cm}^{ - 3} \times 0.857 {cm}^{3} [/tex]
[tex]m = 0.857g[/tex]


Hence the fish tank can hold 0.857g water.

Answer:

8572.5 grams of the water will fish tank can hold.

Explanation:

Volume of the fish tank = V

Length of fish tank = l = 30 cm

Width of fish tank = w  = 0.075 m = 7.5 cm

1 m = 100 cm

Length of fish tank = h = 15 inches = 38.1 cm

1 inch = 2.54 cm

[tex]V=l\times w\times h=30 cm\times 0.075 cm\times 38.1 cm=85.725 cm^3[/tex]

Volume of fish tank = Volume of water = v = [tex]8572.5 cm^3[/tex]

Mass of water in the tank = m

Density of the water [tex]d= 1 g/cm^3[/tex]

[tex]D=\frac{m}{v}[/tex]

[tex]m=d\times v=1 g/cm^3\times 8572.5 cm^3=8572.5 g[/tex]

8572.5 grams of the water will fish tank can hold.
