Suppose you dissolve 4.75 g of another solid (not urea) in 50.0 mL of water. You note that the temperature changes from 25.0 °C

torisob [31]

Answer:

Mass of the solution = 54.75 g

Explanation:

Mass of solid dissolved = 4.75 g

Mass of the solution = Mass of solid dissolved + Mass of water.

Mass of water = Volume x Density

Volume = 50 mL = 50 cm³

Density = 1 g/cm³

Mass of water = 50 x 1 = 50 g

Mass of the solution = 4.75 + 50 = 54.75 g

A solar cell that transforms 300 J of light energy into 45 J of electrical energy and 255 J of wasted energy. whats the efficien

Setler [38]

Answer:

15%

Explanation:

Step one:

Given data

Energy source= 300J

Useful energy = 45J

Waste energy = 255J

Required

The efficiency of the solar system

Step two:

The efficiency is computed by factoring only the useful work and the energy source

Efficiency= 45/300*100

Efficiency= 0.15*100

Efficiency= 15%
