<span>There are a number of ways to express concentration of a solution. This includes molarity. It is expressed as the number of moles of solute per volume of the solution.  To convert the mass of the solute to moles, we use the molar mass of the substance. We calculate as follows:

MOlarity = 4.725 g ( 1 mol / 58.45 g ) / .5 L = 0.162 mol / L</span>

During the first half of the 20th century, the theory of plate tectonics was developed. Evidence supporting this theory included
Makovka662 [10]

A) GPS monitoring and satellite imagery of crustal movements

Explanation:

The most recent evidence supporting the theory of plate tectonics is the use of  GPS monitoring and satellite imagery of crustal movements.

GPS denotes Global Positioning Systems.

Satellite imagery is a recent advancement in the study of moving plates.

  • The global positioning system uses the position of a system of satellites in space to delineate positions on earth.
  • It works on the principles of triangulation and this helps to fix positions of objects on the earth surface.
  • With this, the change in position of the plates can be recorded by known fixed positions of objects.
  • Satellite imagery helps to map changes in terrain with time.
  • Images can be correlated through time and the shift in terrains delineated.

When 28242 J are transferred to water sample, its temperature increases 18⁰C to 63⁰C. Determine the mass of the water sample.
ivanzaharov [21]

Answer:

149.79

Explanation:

Formula

Joules = m * c * delta (t)

Givens

J = 28242

m = ?

c = 4.19

Δt = 63 - 18 = 45

Solution

28242 = m * 4.19 * 45

28242 = m * 188.55

m = 28242 / 188.55

m = 149.79
