I have a balloon that can hold 125,000 mL of air. If I blow up this balloon with 3 moles of oxygen gas at a

matrenka [14]

Answer:

234.35 °C

Explanation:

Given data:

Volume of balloon = 125000 mL

Moles of oxygen = 3 mol

Pressure = 1 atm

Temperature = ?

Solution:

Formula:

PV = nRT

P = Pressure

V = volume

n = number of moles

R = ideal gas constant

T = temperature

Volume of balloon = 125000 mL × 1 L /1000 mL

Volume of balloon = 125 L

Now we will put the values:

Ideal gas constant = R = 0.0821 atm.L/mol.K

PV = nRT

T = PV/nR

T = 1 atm × 125 L/ 0.0821 atm.L/mol.K × 3 mol

T= 125 /0.2463 /K

T = 507.5 K

K to °C

507.5 K - 273.15 = 234.35 °C

if the density of water is 1 g/ml, what would happen to an object with a mass of 80 g and a volume of 100 cubic cm when you plac

Nastasia [14]

Answer:

that object will float on the water

Explanation:

Since the density of water is greater than that of the object , the object will float on the water.

NB. Density of the object=

$\frac{mass}{volume}$

Given that mass of the object is 80g and volume 100cm^3

substituting them in the formula

Density=80g/100cm^3

Density=0.8g/cm^3

since 0.8<1 which is the density of the object and water respectively, the object will float.
