Answer: How to calculate the mass percent by using these instructions
1.The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).
2.The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
Explanation:
Answer:
Same number of valance electrons
Explanation:
All of them are in group 1 so they have 1 valance electron.
If they were in same period they would have same number of energy levels.
2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.
It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.
They just are very cute tho and cute and funny and
Gravity causes mass wasting.
