A because chem is so cool and when you do that it equals the correct answer
Answer:
There are 2.258 x 10^24 molecules of CO2 in 165 grams of CO2.
Explanation:
First you have to calculate the molar mass of carbon dioxide ⇒ 44 grs/mol. Then,
44 grs ------------- 1 mol CO2
165 grs ------------ x = 3.75 moles of CO2.
Then, from Avogadros constant we have that there are 6.022 x 10^23 molecules in 1 mol. So,
1 mol CO2 ---------------- 6.022 x 10^23 molecules CO2
3.75 moles CO2-------- x = 2.258 x 10^24 molecules CO2.
There are 2.258 x 10^24 molecules CO2 in 165 grams of CO2.
Actually the answe is mass.
Answer:
a car traveling 60 miles per hour
Explanation:
The plant will grow less than 5 centimeters because it is a seedless, non-vascular plant. The correct option is B.
<h3>What are moss plants?</h3>
Moss plants are those plants that do contain seeds or flowering plants. They are non-vascular plants, and they maintain the moisture of the soils. They are very small plants.
Moss plants are small plants that grow in moist and humid conditions. They do not need so much sunlight. They will grow less than 5 centimeters and wet conditions.
Thus, the correct option is B. less than 5 centimeters because it is a non-vascular plant.
