4 0

Answer:

v = 1.5 m/s

Explanation:

Given that,

Distance covered by a person, d = 105 m

Time taken, t = 70 s

We need to find the average speed of the person. We know that the average speed is given by :

v=\dfrac{d}{t}\\\\v=\dfrac{105\ m}{70\ s}\\\\v=1.5\ m/s

So, the average speed of the person is equal to 1.5 m/s.

What mass of nitrous oxide gas (N2O) is contained in 20.0 L balloon at a pressure of 110.0 kPa and a temperature of 25 C?
likoan [24]

Answer:

40.94 g

Explanation:

Given data:

Mass of NO₂ = ?

Volume = 20.0 L

Pressure = 110.0 Pka

Temperature = 25°C

Solution:

Pressure = 110.0 KPa (110/101 = 1.1 atm)

Temperature = 25°C (25+273 = 298.15 K)

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

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

T = temperature in kelvin

n = PV/RT

n = 1.1 atm × 20.0 L / 0.0821 atm.L/ mol.K ×298.15 K

n = 22 / 24.5 /mol

n= 0.89 mol

Mass of NO₂:

Mass = number of moles × molar mass

Mass = 0.89 mol × 46 g/mol

Mass = 40.94 g

How many grams of o2(g) are needed to completely burn 70.2 g of C3H8(g)
Lubov Fominskaja [6]
First you must write a balanced chemical equation.

C3H8 + 5O2 --> 3CO2 + 4H2O

From there, we can set up the stoichiometry equation to solve.

g O2= 70.2 g C3H8 X (1 mol C3H8/44.0962g C3H8) X (5 mol O2/1 mol C3H8) X (31.998g O2/1 mol O2)

Now solve, and you should get 254.7 g O2. Hope this helped!
