Answer:
6.28 L
Explanation:
Given data:
Volume of NO₂ = ?
Mass of NO₂ = 12.9 g
Temperature and pressure = ?
Solution:
First of all we will calculate the number of moles of gas.
Number of moles = mass/molar mass
Number of moles = 12.9 g/ 46 g/mol
Number of moles = 0.28 mol
At standard temperature and pressure 1 mole of gas occupy 22.4 L volume.
Thus,
0.28 mol × 22.4 L/1 mol
6.27 L ≅ 6.28 L
Answer:
0.47m²
Explanation:
Given parameters:
Length = 9.025 x 10⁶m
Width = 5.215 x 10⁻⁸m
Unknown:
Area of the rectangle = ?
Solution:
Area is the derived from the product of the length and width of a body.
Area = length x width = 9.025 x 10⁶m x 5.215 x 10⁻⁸m
Area = 0.47m²
It is called a hypothesis.
It's been a while... but I'm <em>pretty</em> sure it's
H₂O₄
It is 50. The answer is 50. 10x5=50 50x1=50
