Answer:
Measuring the mass of metal used in a reaction
Explanation:
A quantitative observation is one in which you use numbers to measure a property.
You would use numbers to record the mass of a metal, e.g., 1 g.
You would use words to describe the colour of a solid, the feel of a liquid, and the niceness of an odour.

Answer : The final pressure will be, 666.2 mmHg
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 790 mmHg
= final pressure = ?
= initial volume = 101.2 mL
= final volume = 120 mL
Now put all the given values in the above equation, we get:
Therefore, the final pressure will be, 666.2 mmHg
