How many liters is 1.9 mol of Cl2 at STP?
Lena [83]

Answer:

V = 42.6 L

Explanation:

Given data:

Number of moles of Cl₂ = 1.9 mol

Temperature and pressure = standard

Volume occupy = ?

Solution:

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

By putting values,

1 atm ×  V = 1.9 mol ×0.0821 atm.L /mol.K × 273.15 k

V = 42.6  atm.L / 1 atm

V = 42.6 L

The acceleration of a sprinter is 10 m/s2. The force exerted on the starting blocks is 650 N. What is the mass of the sprinter?
jek_recluse [69]

The relation between force, mass of an object and its acceleration is given by following equation

F = mass of object X acceleration

The unit of Force is Newton (N)

unit of acceleration is ms⁻²

unit of mass if Kg

[all these are SI units]

Mass of object =\frac{Force}{acceleration}

mass of sprinter =\frac{650}{10}=65kg
