Explanation:
6.02×1023 culture atoms have a mass of 63.5g. 12.0g. c +23.0g O2__44.0g CO2.(12.0+16.0+16.0=44.0g).1 mol 1 mol. 1 mol number molecules weight
Answer : The molar concentration of ethanol in the undiluted cognac is 8.44 M
Explanation :
Using neutralization law,
where,
= molar concentration of undiluted cognac = ?
= molar concentration of diluted cognac = 0.0844 M
= volume of undiluted cognac = 5.00 mL = 0.005 L
= volume of diluted cognac = 0.500 L
Now put all the given values in the above law, we get molar concentration of ethanol in the undiluted cognac.
Therefore, the molar concentration of ethanol in the undiluted cognac is 8.44 M
The answer is A because it gets caught in clouds then is let down in rain
Answer:
The most appropriate unit to use for a redwood is:
Explanation:
The largest tree in the world is called Hyperion and it is a <em>Sequoia sempervirens</em>, that is to say, a redwood, which measures a little more than 115 meters, when knowing this data first hand, you can imagine that <u>the vast majority of trees are usually measured in meters since their size is usually one meter in ahead (although you should know that there are some shrub species that can measure only centimeters, but being a minority, the meter unit is usually used)</u>.
