57.1g * 6.022*10^23 / 22.9 * 2 = 7.51*10^23 molecules
Answer:
pH = - log [2.12 x 10^-3]
what is the log of 2.22 x 10^-3]
Take the opposite of that,
That is the pH, now, just make certain you use the correct significant figures.
Explanation:
The main environmental factors that affect microorganism growth include chemical inhibitors, oxygen, pH, nutrients, moisture and temperature.
<h3>What are micro organism?</h3>
Micro Organism are organism that can be seen with a microscope.
Microorganisms include bacteria, protozoa, algae, and fungi.
Micro organisms exist in its single-celled form or as a colony of cells.
The main environmental factors that affect microorganism growth include chemical inhibitors, oxygen, pH, nutrients, moisture and temperature.

Answer:
Electrons, Protons, and Neutrons. ... Protons are another type of subatomic particle found in atoms. They have a positive charge so they are attracted to negative objects and repelled from positive objects. Again, this means that protons repel each other
1.) Convert grams of glucose to moles of glucose:25.5g gluc. * (1 mol/180g gluc.) = 1.41E-1 mol gluc. Note. Molar mass gluc. = 180g/mol
2.) Convert grams of solvent to kilograms of solvent:398 g H2O * (1kg H2O/1000g H2O) = 0.398 kg H2O
3.) Determine molality (moles solute/kilogram solvent) of solux:1.41E-1 mol gluc./0.398 kg H2O = 3.5427E-1 mol/kg
4.) Employ Freezing Point Depression equation and determine the freezing point of the solux:
ΔT = i Kf mΔT= ? (°C)Kf = 1.86 (°C kg mol¯1)m = 3.5427E-1 (mol/kg)i = (assumed negligible)
ΔΤ = (1.86)(3.5427E-1)ΔT = 6.589Ε-1°C
5.) ΔT = 6.589Ε-1°C
25.5g gluc. * (1 mol/180g gluc.) = equal 0.14166, not 1.41E-1 mol glucose
