Explanation:
Amount of water required in each case:
(a)The mass% of the solution is:9.95
Mass of solute that is urea is 6.80 g
To determine the mass of solvent water use the formula:
Hence the mass of solvent = mass of solution - the mass of solute
=68.3 g - 6.80g
=61.5 g
Hence, the answer is mass of solvent water required is 61.5 g.
(b) Given mass%=1.70
mass of solute MgBr2 = 29.3 g
The mass of solvent water required can be calculated as shown below:
The mass of the solution is 1720 g.
Mass of solvent water = mass of solution - mass of solute
=1720 g - 29.3 g
=1690.7 g
Answer: The mass of water required is 1690.7 g.
A cherry red complexion would be the least trustworthy result when evaluating a client who had carbon monoxide poisoning suspicions.
Carbon monoxide poisoning:
- When present in sufficient quantity in the surrounding air, the odorless, colorless, and toxic gas known as carbon monoxide (CO) can result in rapid sickness and death. Using alternative fuels or electrical for warming, chilling, or cooking during power outages during situations like storms or winter storms can result in carbon monoxide(CO) buildup in a house, carport, or camper, which can harm the occupants and their pets.
- It is never a good idea to use a generator, grill, camp stove, or any other appliance that burns fuel, kerosene, natural gas, or charcoal inside a house, basement, garage, camper, or even outside next to an apartment window or windows air conditioner.
- Carbon monoxide poisoning can cause a variety of non-specific symptoms and indications. Migraine, vertigo, fatigue, vomiting, sickness, chest discomfort, and altered mental state are the most typical signs of CO poisoning.
