Question

A graduated cylinder contains 18.0ml of water. what is the new water level after 35.6g of silver metal with a density of 10.5 g/ml is submerged in the water?

2.a thermometer containing 8.3g of mercury has broken. if mercury has a density of 13.6 g/ml what volumn spilled.

3. a fish tank holds 345gal of water. using the density of 1.0 g/ml for water, determine the number of pounds of water in the fish tank.

Answer 1

The answer to your question is

1.- Volume = 3.4 ml

2.- Volume = 0.61 ml

3.- Mass = 2872.8 pounds

Step-by-step explanation:

Problem 1

Volume = 18 ml

mass = 35.6 g

density = 10.5 g/ml

Process

1.- Calculate the volume of silver

Formula

`density = (mass)/(volume)`

solve for volume

`volume = (mass)/(density)`

Substitution

`volume = (35.6)/(10.5)`

volume = 3.4 ml

2.- Problem 2

Total volume = ?

Volume = 18 + 3.4

Volume = 21.4 ml

Data

mass = 8.3 g

density = 13.6 g(ml

volume = ?

Formula

`density = (mass)/(volume)`

Solve for volume

`volume = (mass)/(density)`

Substitution

`volume = (8.3)/(13.6)`

Result

volume = 0.61 ml

3.- Problem 3

Data

volume = 345 gal

density = 1 g/ml

mass = ?

Formula

`density = (mass)/(volume)`

Solve for mass

mass = density x volume

Covert gal to ml

1 gal --------------- 3785 ml

345 gal ------------- x

x = (345 x 3785) / 1

x = 1305825 ml

Substitution

mass = 1 x 1305825

mass = 1305825 g

Convert g to pounds

1 g ------------------- 0.0022 pounds

1305825 g ---------------- x

x = (1305825 x 0.0022)

x = 2872.8 pounds
