Blood alcohol concentration (BAC) is a measure of alcohol in your body, expressed as grams of alcohol per 100ml of blood. For a
ella [17]

Answer:

A 71 kg person will get a BAC of 0.05 when drinking 0.3442 L of beer

Explanation:

  • The mass of blood in a human body is approximately 8%, so if a person weighs 71 kg, the mass of blood would be:

71 kg * 8/100 = 5.68 kg of blood.

  • Using <u>blood density</u>, we can calculate the volume that 5.68 kg of blood occupies:

5.68 kg * \frac{1m^{3}}{1025kg} = 0.0055415 m³

We convert m³ into mL, keeping the unit that we want to convert to in the numerator; and the unit that we want to convert in the denominator:

0.0055415m^{3}*\frac{1000L}{1m^{3}} *\frac{1000mL}{1L}=5541.5mL

  • Now we <u>calculate the amount of alcohol that would be needed in the bloodstream</u> to get a BAC of 0.05:

\frac{5541.5mL}{100mL}*0.05g = 2.77 g of alcohol are needed in the bloodstream in order to have a BAC of 0.05

  • The amount of <u>alcohol that needs to be ingested</u> is higher than 2.77 g, due to the fact that only 17% of the alcohol goes into the bloodstream, so:

2.77 g *\frac{100}{17} = 16.29 g of alcohol need to be ingested

  • Then we use the alcohol concentration of beer to calculate the volume of beer needed, using the alcohol density. First we <u>convert the alcohol density to g/L</u>, making sure the units that we want to convert cancel each other:

789\frac{kg}{m^{3}}*\frac{1000g}{1kg} *\frac{1m^{3}}{1000L}  =789g/L

  • Now we use the density to <u>calculate the litres of alcohol needed</u>, keeping in mind that 16.29 g of alcohol are needed:

16.29g*\frac{1L}{789g}= 0.02065 L of alcohol are needed.

  • Finally we <u>calculate the litres of beer needed</u>, keeping in mind the concentration of alcohol in beer:

0.02065L_{alcohol}*\frac{100L_{beer}}{6L_{alcohol}} =0.3442 L of beer are needed.

Determine the correct Lewis structure for ammonia (NH3). Note: Hydrogen and nitrogen have one and five valence electrons respect
Tresset [83]
The lewis structure is helpful in showing how the bonding between atoms of a molecule are. The lewis structure of ammonia would be that the nitrogen atom will share three pairs of electron with the three hydrogen atoms leaving nitrogen to have 1 lone pair.<span />

) what happens when CO2 passed over time water<br>for short period of time? Explain​
aniked [119]

Answer:

 When carbon dioxide is passed through lime water for a short time,it turns lime water milky due to formation of a white precipitate of calcium carbonate.

Explanation:

Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.
