The density of silver is 10.5 g/cm3.
Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
Answer:
oxygen molecule
Explanation:
I belive it is oxygen molecule
<u>Answer:</u> The mass of potassium benzoate is 
<u>Explanation:</u>
To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

We are given:
Molarity of solution = 0.120 M
Molar mass of potassium benzoate trihydrate = 214.26 g/mol
Volume of solution = 1.5 L
Putting values in above equation, we get:

Hence, the mass of potassium benzoate is
