Airida [17]3 years ago
5 0

Answer:

Explanation:

Given parameters:

Density of cobalt = 8.9gcm⁻³

Mass of cobalt = 17.8g

Solution

Density can be defined as the mass per unit volume of a substance:

                      Density = \frac{mass in g}{volume in cm^{3} }

The unknown in the problem is Volume:

                    Volume = \frac{mass}{Density}

                     Volume =   \frac{17.8}{8.9} = 2cm³

State Boyle's, Charles's, and Gay-Lussac's laws using sentences, then equations
dimaraw [331]

Explanation:

1. Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

P\propto \frac{1}{V}      (At constant temperature and number of moles)

P_1\times {V_1}=P_2\times V_2

2. Charles' Law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T    (At constant pressure and number of moles

\frac{V_1}{T_1}=\frac{V_2}{T_2}

3. Gay Lussac's Law states that tempertaure is directly proportional to the pressure of the gas at constant volume and number of moles of gas

P\propto T    (At constant volume and number of moles)

\frac{V_1}{n_1}=\frac{V_2}{n_2}
