Considering the definition of mass volume percentage, the percent concentration of dextrose is 45%.

<h3>Mass volume percentage</h3>

Mass volume percentage (% m/V) is a measure of concentration that indicates the number of grams of solute per 100 volume units of the solution. In other words, the volume percent of a component in the solution is defined as the ratio of the mass of the component to the volume of the solution, expressed as a percentage.

The mass volume percentage of a solution is determined by the following expression:

Mass volume percentage=\frac{mass of solute}{volume of solution}x100

<h3>Percent concentration in this case</h3>

In this case, you know:

  • mass of solute= 450 grams
  • volume of solution= 1 L= 1000 mL

Replacing in the definition of mass volume percentage:

Mass volume percentage=\frac{450 grams}{1000 mL}x100

Solving:

<u><em>mass volume percentage= 45%</em></u>

Finally, the percent concentration of dextrose is 45%.

What two forces act in the nucleus to create a 'nuclear tug-of-war'?
Alex787 [66]

Answer:

Electrostatic repulsion, strong nuclear force

Explanation:

The nucleus consists of protons and neutrons. protons are positively charged while neutrons possess no charge.

Since protons are positively charged, they repel each other strongly (like charges repel). This strong repulsion of like charges makes the nucleus somewhat unstable leading to spontaneous fission of heavy nuclei.

However, an opposing force called nuclear attractive force tends to hold the nucleons together. This attraction occurs when two nucleons are bonded by a particle called a π meson.

Hence, the two forces that act in the nucleus to create a  'nuclear tug-of-war' are electrostatic repulsion and a strong nuclear force.

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2.
Ivanshal [37]

Answer:

Mass is the same but it weights 64 Newtons

Explanation:

First of Mass is the same in any sort of gravity. Now let's calculate weight

W = MG

where W = Weight

M = Mass

G = Gravity

W = (40kg)(1.6)

W = 64

Sorry for the spelling mistakes, hope this helps
