The density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.
<h3>How to calculate density?</h3>
The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;
Density = mass ÷ volume
According to this question, a piece of metal with a mass of 17.1 g was dropped into a graduated cylinder containing 17.00 mL of water. The density can be calculated as follows:
Density = 17.1g ÷ 17.00mL
Density = 1.005g/mL
Therefore, the density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.

Answer:
First one: Yes, It can be negative.
Explanation:
First one: The reason you can have negative acceleration is that acceleration can slow down, or decelerate, causing the negative acceleration.
Answer : The volume of gas occupy at a pressure of 18 psi is, 520.8 mL
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 = 12.5 psi
= final pressure = 18 psi
= initial volume = 750 mL
= final volume = ?
Now put all the given values in the above equation, we get:
Thus, the volume of gas occupy at a pressure of 18 psi is, 520.8 mL
Answer:
T=√250 or ≈15.81
Explanation:
by dividing both sides by .008, you eliminate .008 on the left side and get 2÷.008=250 on the right. to eliminate the ^2 on T, you need to square root both sides, so on the left it's √T^2=T, and on the right it's √250, or roughly 15.81.
