Answer:
82.9 mL
Explanation:
1. Volume of silver
2. Volume of gold
3. Total volume of silver and gold
V = 4.766 mL + 2.591 mL = 7.36 mL
4 New reading of water level
V = 75.5 mL + 7.36 mL = 82.9 mL
Answer:
Risk management
Explanation:
Risk communication is exchange of the advice, real-time information and the opinions between the experts and the people which are facing threats to their economic, health, or well-being.
Risk assessment is overall process where the hazards and the risk factors which have potential to cause the harm is identified.
Risk perception is subjective judgement which people/ experts make about characteristics and the severity of the risk.
Risk management is evaluation, identification and prioritization of the risks followed by the coordinated and the economical application of the resources to monitor, minimize and control probability of the unfortunate events.
Thus, Option D is correct because in risk management, a Quantitative Solution is given to decrease risk level like to recycle the plastic.
5.0x10^1 kg is the correct answer
Answer:
1.32 moles.
Explanation:
From the question given above, the following data were obtained:
Density of Al = 2.70 g/cm³
Volume of Al = 13.2 cm³
Number of mole of Al =.?
Next, we shall determine the mass of Al.
This can be obtained as follow:
Density of Al = 2.70 g/cm³
Volume of Al = 13.2 cm³
Mass of Al =?
Density = mass / volume
2.7 = mass of Al / 13.2
Cross multiply
Mass of Al = 2.7 × 13.2
Mass of Al = 35.64 g
Finally, we shall determine the number of mole of Al. This can be obtained as follow:
Mass of Al = 35.64 g
Molar mass of Al = 27 g/mol
Number of mole of Al =?
Mole = mass / molar mass
Number of mole of Al = 35.64 / 27
Number of mole of Al = 1.32 moles
Thus, 1.32 moles of aluminum are present in the block of the metal.
