The number of mole of ethanol, CH₃CH₂OH the chemist will use in the experiment is 0.65 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mole of CH₃CH₂OH</h3>
From the question given above, the following data were obtained:
- Mass of CH₃CH₂OH = 30 g
- Molar mass of CH₃CH₂OH = 12 + (1×3) + 12 + (1×2) + 16 + 1 = 46 g/mol
Mole = mass / molar mass
Mole of CH₃CH₂OH = 30 / 46
Mole of CH₃CH₂OH = 0.65 mole

The hazard of the food worker that is most likely to make pasta unsafe to eat is;
A; Torn packaging fragments
Complete question is;
A food worker washes her hands before taking a torn package of dry pasta from the food storage area. She dumps the pasta In the stainless pot to cook.
What hazard is most likely to make pasta unsafe to eat?
A. Torn packaging fragments
B. Metal leaching from the pot
C. Pathogens from the worker’s hand
D. Soap residue from the worker’s hands
Food contamination can occur during packaging and storage of processed foods if the different quality standards that need to be followed are not observed.
Now, we are told that the package of dry pasta was torn before she put it into the stainless pot to cook. This means that ounce she washed her hands there is not likely to be any microbiological contamination but instead there will be chemical contamination that arises from fragments of the torn pasta package which could have entered inside it before putting into the cooking pot.
In conclusion, the hazard likely to have occurred to make the package unsafe to eat is called Torn packaging fragments.
