Answer:

The correct option is (c).

Explanation:

Electromagnetic waves are created as an interaction of the electric field and a magnetic field.

The characteristics of a wave are amplitude, frequency, speed and wavelength. It term defines a wave.

All the electromagnetic wave moves with a common speed i.e. the speed of light.

Hence, all electromagnetic waves move at the same speed.

. Find the mass of 2.61 moles of H2O2.

charle [14.2K]

Mass of H₂O₂ = 88.778 g

<h3>Further explanation</h3>

The mole itself is the number of particles contained in a substance amounting to 6.02.10²³

Mole can also be determined if the amount of substance mass and its molar mass is known

$\large {\boxed {\boxed {\bold {mol = \frac {mass} {molar \: mass}}}}$

moles of H₂O₂ = 2.61

So the mass of H₂O₂(MW=34,0147 g/mol) :

$\tt mass=mol\times MW\\\\mass=2.61\times 34,0147 g/mol\\\\mass=88.778~g$

How scientific notation makes it easier to work with very large or very small numbers.

Elan Coil [88]

Say that you have 100³

instead of writing and solving 100x100x100 three times to solve it, you can just write 100³

the exponents in scientific notation make the whole process easier.
