What distance does electromagnetic radiation travel in 33 fs?

Chemistry
1 answer:
umka2103 [35]3 years ago
4 0

<u>Given:</u>

Time taken by the electromagnetic radiation, t = 33 fs

<u>To determine:</u>

The distance (d) travelled

<u>Explanation:</u>

Time taken = 33 fs (femtosecond)

1 fs = 10⁻¹⁵ s

Thus t = 33 *10⁻¹⁵ s

Speed of electromagnetic radiation = 3*10⁸ m/s

Distance = Speed * Time = 3*10⁸ ms-1 * 33*10⁻¹⁵ s = 99*10⁻⁷ m

Ans: distance traveled = 9.9*10⁻⁶ m

What is the volume in liters of 3.80 moles of CO2gas at STP?
pantera1 [17]

Answer:

V = 85.2

Explanation:

STP = 273K and 1 atm

Considering what we know about STP, we get the moles, temperature, and pressure. Using the ideal gas law we can find the volume (PV = nRT). Plug in our variables: (1 * V = 3.80 * R * 273). Since we are dealing with atm and not kPA or mmHg, we use the constant for atm (0.0821) which we use for R. (So.. now our equation is 1 * V = 3.80 * 0.0821 * 273). We now multiply the right side to get 85.17054. So... V = 85.2 considering sigificant figures (this is the part where I am the least sure of, since I havent done sig figs in a while)

If the volume of a solution is 25.6 L and its molarity is 8.20 M, how many moles of solute are
harkovskaia [24]

Answer:

210 moles

Explanation:

From the question given above, the following data were obtained:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:

Molarity = mole /Volume

With the above formula, the mole of solute dissolved can be obtained as follow:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity = mole /Volume

8.20 = mole / 25.6

Cross multiply

Mole = 8.20 × 25.6

Mole = 209.92 ≈ 210 moles

Thus, the mole of solute dissolved in the solution is 210 moles
