moles S = 425 g / 32.066 g/mol=13.2
<span>the ratio between S and O2 is 1 : 1 </span>
<span>moles O2 required = 13.2 </span>
<span>Volume of O2 at STP = 13.2 mol x 22.4 L/mol=295.7 L</span>
The smallest unit that behaves like the substance is an atom.
Wavelength and Frequency are inversely related to each other as,
υ = c / λ ----- (1)
Where;
υ = Frequency = 2.40 × 10¹³ s⁻¹
c = 2.99 × 10⁸ ms⁻¹
λ = ?
Solving equation 1 for λ,
λ = c / υ
Putting Values,
λ = 2.99 × 10⁸ ms⁻¹ ÷ 2.40 × 10¹³ s⁻¹
λ = 0.00001245833 m
Or,
λ = 1.24 × 10⁻⁵ m
Answer:
The answer is
<h2>4.5 × 10²²</h2>
Explanation:
To find the number of atoms of titanium , given it's number of moles we use the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 0.075 mol
We have
N = 0.075 × 6.02 × 10²³
We have the final answer as
<h3>4.5 × 10²²</h3>
Hope this helps you
