Thank you
Answer:
- <u>You need to convert the number of atoms of Ca into mass in grams, using Avogadro's number and the atomic mass of Ca.</u>
Explanation:
The amount of matter is measured in grams. Thus, you need to convert the number of atoms of Ca (calcium) into mass to compare with 2.45 grams of Mg.
To convert the atoms of calcium into mass, you divide by Avogadro's number, to obtain the number of moles of atoms, and then divide by the atomic mass of calcium.
<u />
<u>1. Number of moles, n</u>

<u />
<u>2. Mass</u>
- mass = number of moles × atomic mass
- mass = 0.053969mol × 40.078g/mol = 2.16g
Then, 2.45 g of Mg represent a greaer mass than the 3.25 × 10²² atoms of Ca.
Answer:
403 Seconds in Minutes is about 6 minutes.
Explanation:
Now, because I don't know if you're labeling your 1500 as meters or miles, I'm assuming it's miles.
I'm going to take a gander at your question.
Since you're technically going so fast for some odd reason.
Your answer should most definitely be 403 MPH
Answer:
it would increase to twice what it was
Answer:
A. Both describe ways a solid can change.
