Answer:
The answer to your question is 3 moles of CO
Explanation:
Data
mass of CO = ?
moles of O₂ = 1.50
Balanced chemical reaction
2C + O₂ ⇒ 2CO
Process
To solve this problem use proportion and cross multiplication. Use the coefficients of the balanced equation.
1 mol of oxygen ------------------ 2 moles of CO
1.5 moles of oxygen ----------- x
x = (1.5 x 2) /1
-Simplification
x = 3 / 1
-Result
x = 3 moles of CO

Answer:
Mass = 75.6 g
Explanation:
Given data:
Temperature of gas = 17°C
Volume of gas = 575 mL
Pressure of gas = 85000 mmHg
Mass of gas = ?
Solution:
Temperature of gas = 17°C (17+273 =290 K)
Volume of gas = 575 mL (575/1000 = 0.575 L)
Pressure of gas = 85000 mmHg (85000/760 = 111.8 atm)
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
111.8 atm × 0.575 L = n×0.0821 atm.L/ mol.K × 290 K
64.285 atm. L = n×23.809 atm.L/ mol
n = 64.285 atm. L / 23.809 atm.L/ mol
n = 2.7 mol
Mass of nitrogen gas:
Mass = number of moles × molar mass
Mass = 2.7 mol × 28 g/mol
Mass = 75.6 g
The standard state of the elements Nitrogen and Oxygen are N2 and O2, knowing that they are diatomic elements. With that piece of information, the unbalanced equation for the formulation of NO2(g) should be as follows -
N2 + O2 ---> NO2
And if you include their states -
N2 ( g ) + O2 ( g ) ---> NO2 ( g )
To balance this chemical equation consider the number of reactants and products on other side of the equation. If you were to include a coefficient of one - half with respect to N2 on the reactant side, it would balance the reactants and products -
