The density formula is mass divided by the volume. The mass in this case is 19 grams and the volume 25 ml.
The density is 0,76 g/ml.
Answer:
1.4 moles/ 2.0 L= 0.7 M
Explanation: Molarity= moles of solute/ Liters of solution
therefore just plug the numbers in and you'll find the molarity to equal. 0.7
<span>divide the 201g by the mol mass of the compound. Just add up the masses of the various element</span>
Answer:
It is known that 1 mol of a molecule contains 6.023×1023 6.023 × 10 23 number of molecules. So, 0.25 moles of CO2 C O 2.
