How do you determine how much alum can be dissolved in 10 ml of hot deionized water to make a saturated solution??

You need to monitor the solution to see when the crystals start gathering at the bottom of the solution. You can slowly add alum until it stops dissolving. The point just before it starts its sedimentation at the bottom is the point when the solution is saturated.

The total volume in milliliters of a glucose-water solution is given by the equation below: V = 1001.93 + 111.5282m + 0.64698m^2
vagabundo [1.1K]

Answer:

a. Vₐ = 111.5282 + 1.29396m

b. For m = 0.100m; Vₐ = 111.6576

Explanation:

The partial molar volume of compound A in a mixture of A and B is defined as :

V_a = \frac{dV}{dn_a}

Where V is volume and n are moles of a.

a. As molality is proportional to moles of substance, partial molar volume of glucose can be defined as:

Vₐ =  dV / dm =  d(1001.93 + 111.5282m + 0.64698m²) / dm

<em>Vₐ = 111.5282 + 1.29396m</em>

b. Replacing for m = 0.100m:

Vₐ = 111.5282 + 1.29396×0.100

<em>Vₐ = 111.6576</em>

<em></em>

I hope it helps!

What is the volume of 8.50 moles of hydrogen gas?
Cerrena [4.2K]
Okay! 
8.50molH, represents 8.50 moles of Hydrogen gas!

To convert from moles to volume multiply it by the ratio of L/molH
mol of anything in a conversion problem is always 1 unless you are going to an unknown! Try to memorize this, but the number you always put in for the # of liters in a conversion problem is 22.4L (L is a measure of volume) 

8.50molH * (22.4 L/ 1 molH)

190.L of Hydrogen Gas. 

Hope that helped!

This is thermal conduction.
In conduction area with higher kinetic energy (in this case how water) transfer thermal energy to an area with lower kinetic energy (in this case frozen vegetables).
