How many atoms are in 131.97 liters of water vapor at STP?

1 answer:

3 0

At STP, 1 mol of gas has 22.4 L. First convert to moles using this conversion factor.
Then use Avogadro's number to convert to molecules of water (1 mol = 6.02 x 10^23 particles).
Then, there are 3 atoms in each molecules of water (2 H + 1 O). Use this to convert to atoms.

A military jet cruising at an altitude of 12.0km and speed of 1300./kmh burns fuel at the rate of 46.2/Lmin. How would you calcu

ira [324]

Answer:

2,452.12 L of fuel the jet consumes on a 1150 km mission.

Explanation:

Speed of the jet = 1300 km/h

1 hour = 60 minutes

$1300 km/h=\frac{1300 km}{60 min}=21.667 km/min$

Rate at which jet consumes fuel = 46.2 L/min

Distance covered by jet by consuming 1 liter fuel or mileage = R

R = $\frac{21.667 km/min}{46.2 L/min}=0.4690 km/L$

The amount of fuel the jet consumes on a 1150 km mission will = V

Amount of fuel = $\frac{Distance}{Mileage}$

$V=\frac{1150 km}{0.4690 km/L}=2,452.12 L$

2,452.12 L of fuel the jet consumes on a 1150 km mission.

Determine the mass of 2.5 cups of water if the density of water is 1.00 g/cm^3 and 1 cup = 240 mL

jarptica [38.1K]

1) we find out the volume of the water.
Remember: 1 ml=1 cm³
Volume of the water=number of cups x volume of one cup.
Volume of the water=2.5(240 ml)=600 ml=600 cm³

Density=mass/volume ⇒ mass=density x volume

2) we calculate the water mass of 600 cm³ of water.
mass=density x volume
mass=(1 g/cm³)(600 cm³)=600 g.

Answer: the mass of 2.5 cupas of water is 600 g.
