Molality= moles NaCl/ Kg H2O

250 g (1 Kg/ 1000 grams)= 0.250 Kg

Molality= 0.611 moles/ 0.250 Kg= 2.44 molal

The half-life of a radioactive isotope is the amount of time it takes for a quantity of radioactive material to decay to one-hal
finlep [7]

Answer: The statement is true

Explanation:

The half-life of a radioactive isotope is the time taken for half of the total number of atoms in a given sample of the isotope to decay.

For instance

The half-life of radium is 1622 years. This means that if we have 1000 radium atoms at the beginning, then at the end of 1622 years, 500 atoms would have disintegrated, leaving 500 undecayed radium atoms

Thus, the statement is true

Match each physical property of matter to the appropriate definition
Alekssandra [29.7K]

Physical properties of a substance include, solubility, boiling point, etc.

The correct matching of the physical properties with definition is as follows;

  • Solubility - the ability of a substance to dissolve  in another

  • Boiling point - the temperature at which a liquid  becomes a gas

  • Density - the amount of mass in a given volume

  • Buoyant force - the upward force on an object in a  fluid

  • Conductivity - the ability of a substance to transfer  heat or electricity

Above, all the physical properties have been properly matched with the corresponding definitions.
