In 0.7L (700ml) there are 122, 85 grams of NaCl
Scientific notation is: n * 10^a, where n is a number between 1 and 10 ( but not 10 itself ) and a is an integer.
We move decimal place to the left to create a new number from 1 to 10.
Answer:
0.0000250 m = 2.5 * 10^(-5) m.
Answer:
9
Explanation:
mass number = protons + neutrons
= 4 + 5 = 9
The answer to this question should be Carbon dioxide.
To count the molar mass you need to add all the atoms weight that made up the compound. Carbon dioxide or CO2 is made of one carbon and two oxygen. Carbon molecular weight is 12. Oxygen molecular weight is 16. Then if you add them you will got: 12+ 2*16= 12 +32 = 44 g/mole.
