i can not understand the question. There seems to be missing info
Answer:
Mass of liquid unknown liquid = 10.4 g
Explanation:
Volume of liquid = 15 mL
Mass of liquid + graduated cylinder = 55.2 g
Mass of graduated cylinder = 44.8 g
Mass of unknown liquid = ?
Solution:
Mass of unknown liquid is calculated by subtracting the graduated cylinder mass from combined mass of liquid and graduated cylinder.
Mass of liquid = (Mass of liquid + graduated cylinder) - (Mass of graduated cylinder )
Mass of liquid = 55.2 g - 44.8 g
Mass of liquid = 10.4 g
So the mass of unknown liquid is 10.4 g.
Answer:
i think its going to be liquid
Explanation:
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
