Answer:

2.45atm

Explanation:

Use Combined Gas Law: \frac{P_{1}V_{1}}{T_{1}} =\frac{P_{2}V_{2}}{T_{2}}

Solve For P₂: P_{2}=\frac{P_{1}V_{1}T_{2}}{T_{1}V_{2}}

Use Kelvin: 21.0C = 294.15K 29.0 = 302.15K

(1.01atm)(13.0L)(302.15K)=3967.2295

(294.15K)(5.50L)=1617.825

3967.2295/1617.825=2.45219940352 = 2.45 atm

A chunk of copper has a volume of 1.45 mL and a mass of 12.93 grams. What is the density of the chunk of copper?
natta225 [31]

Answer:

Density = 8.92 \ g/mL

Explanation:

The equation for density is:

Density = \frac{mass}{volume}

We plug in the given values:

Density = \frac{12.93 \ g}{1.45 \ mL}

Density = 8.92 \ g/mL
