Answer:-

86.794 K

Explanation:-

Initial temperature T 1 = 32 C + 273 = 305 K

Initial Pressure P 1 = 49.9 KPa

New Pressure P 2 = 14.2 KPa

The Volume remains same since it is rigid.

∴V 1 = V 2 = 50.0 L

Using the relation

P 1 V 1 / T1 = P 2 V 2 / T 2

New temperature T 2 = P 2 V 2 T 1 / ( P 1 V 1)

= 14.2 KPa x 50.0 L x 305 K / ( 49.9 KPa x 50.0 L)

= 86.794 K

What is the density (g / mL) of a substance that has a mass of 8.11 g and, when placed into a graduated cylinder, causes the wat
MAXImum [283]

Answer:

<h3>The answer is 0.42 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 8.11 g

volume = final volume of water - initial volume of water

volume = 44.72 - 25.26 = 19.46 mL

We have

density =  \frac{8.11}{19.46}  \\  = 0.416752312...

We have the final answer as

<h3>0.42 g/mL</h3>

Hope this helps you
