Answer:
Pasteurization involves heating liquids at high temperatures for short amounts of time. Pasteurization kills harmful microbes in milk without affecting the taste or nutritional value (sterilization= all bacteria are destroyed).
Explanation:
A lead ball added to a graduated cylinder containing 30.8 ml of water, causing the level of the water to increase to 89.9 ml, has a volume of 59.1 ml.
Volume is defined as the amount of space that matter occupies. There are three different ways to find the volume:
1) Volume by Space - by measuring its physical dimensions
2) Volume by Density and Mass - by dividing its weight by its density
3) Volume by Displacement - by measuring the volume displaced when immersed in a liquid or gas
To solve for the volume of the lead ball, we can use the displacement method by subtracting the initial volume from the final volume.
If the level of the water increased from 30.8 ml to 89.9 ml upon adding the lead ball, the displaced volume is:
volume = final volume - initial volume
volume = 89.9 - 30.8
volume = 59.1 ml
Hence, the volume of the lead ball, using displacement method, is 59.1 ml.

Answer:
The molar mass of Mg(NO₃)₂, 148.3 g/mol.
Explanation:
Step 1: Given data
- Mass of Mg(NO₃)₂ (solute): 42.0 g
- Volume of solution: 259 mL = 0.259 L
Step 2: Calculate the moles of solute
To calculate the moles of solute, we need to know the molar mass of Mg(NO₃)₂, 148.3 g/mol.
42.0 g × 1 mol/148.3 g = 0.283 mol
Step 3: Calculate the molarity of the solution
M = moles of solute / liters of solution
M = 0.283 mol / 0.259 L
M = 1.09 M
