How mant low dose 81mg aspirin tablets can be made from 1.21 kg of aspirin​
KiRa [710]

Answer:

14,938 tablets.

Explanation:

WE divide:

1.21 kg / 81 mg

1.21 kg = 1,210 g = 1.210,000 mg.

So it is 1,210,000 / 81

= 14,938 tablets.

If 2.5L of solution is diluted to prepare 1.7L of a 0.8M solution, what was the original concentration?
mamaluj [8]

Answer:

0.544 M

Explanation:

First find the moles in the final solution

0.8 mols/L *1.7L

1.36 mols

so there is 1.36 mols in 2.5L

concentration will be 1.36/2.5

0.544 M

One of the postulates of bohr's atomic model of a moving electron is that angular momentum of a moving electron is quantized. Ex
oksano4ka [1.4K]

The angular momentum of an electron in the third Bohr orbit of a hydrogen atom is given by mvr=3h÷2π

<h3>What is momentum?</h3>

Momentum is defined as the amount of motion occurring in something that is moving, or the force that drives something forward to keep it moving.

Bohr never assumed stable electronic orbits with the electronic angular momentum quantized as

l=mvr = \frac{nh}{2pi}

Quantization of angular momentum means that the radius of the orbit and the energy will be quantized as well.

Bohr assumed that the discrete lines seen in the spectrum of the hydrogen atom were due to transitions of an electron from one allowed orbit/energy to another.
