"if 25.0 ml of urine has a mass of 25.725 g and contains 1.929 g of solute, what is the mass/mass percent concentration of solute in the urine sample

To solve this problem we will find the proportion in terms of the solution and solution. According to the data given, the amount of solute is 1,929g in a solution of 25,725g, therefore the mass / mass percentage would be:

Replacing,

Therefore there is 7.499% of solute in the urine sample.

heat the gas and measure the pressure

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
