ayo
you need to just
5.00 x 10^24 ÷ 6.022 x 10^23 = 8.3028894×10^46
^
this is the n number
so the anwer is you bottom feeders is (8.30 moles N)
a. A typical serving of fruits contains an average of about 10 g of carbohydrates.
About 80 % of fruits contain 10 g carbohydrates per serving.
Bananas are high in carbs (20 g/serving) but grapefruit, raspberries, and strawberries are low (5 g/serving).
Answer:
0.39 moles
Explanation:
To find how many moles are in 50.0 g of CaC₂O₄ you divide the grams of the sample by the molar mass of the compound;
=0.39 mol
The grams cancel out and you are left with moles!
I hope this help ^-^
<u>Answer:</u> The volume of concentrated hydrochloric acid required is 16.53 mL
<u>Explanation:</u>
To calculate the volume of concentrated solution, we use the equation:
where,
are the molarity and volume of the concentrated solution
are the molarity and volume of diluted solution
We are given:
Conversion factor: 1 L = 1000 mL
Putting values in above equation, we get:
Hence, the volume of concentrated hydrochloric acid required is 16.53 mL
Answer:
Water displacement is usually the method most students use because if you do it correctly, it can be more accurate than measurement and calculation.
Explanation:
If the object has an abnormal shape, you might be unable to measure its physical dimensions accurately. Instead, what you can do is measure the volume which is displaced when the object is immersed in a liquid or a gas. This is a very common method for measuring volume, and when done correctly, it is highly accurate.
For example, if you want to know the volume of a piece of ginger root, you can fill a beaker or a measuring cup with a known volume of water – let's say one cup. Next, add the ginger. Make sure that it is submerged underwater. Then, measure the new volume at the water line. The new volume will always be more than the starting volume. Subtract the starting volume (one cup) from this new volume, and you will have the volume of the ginger.
