One meter is equal to 10 9 nanometers. How long in meters is 670 nanometers? 6.70 × 10 –7 m
Mila [183]

Answer:

The answer to your question is: the first option

Explanation:

Meter is a unit of length in the SI, international system of units. Its symbol is m.

Nanometer is equivalent to 10⁻⁹ meters, as its name says it is used to measure  extremely small particles.

-To solve this problem we use a rule of three.

                             1 meter      ⇒     10⁹ nanometers

                             x meters    ⇒     670 nanometers

Simplify

                            x = (670 x 1)/( 10⁹)              

                            x = 6.7 x 10 ⁻⁷ meters

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
