Answer:
6.022x10^23 molecules
Explanation:
Since it's one mole of CaCO3, multiply by Avogadro's number to get molecules
Acids have a PH level of 6 or lower
Bases have a PH of 8 or higher
PH 7 is neutral
A. Proton acceptor and this is according to the bronsted Lowry theory
Answer:119.38 g/mol
Explanation:
Add the Molar mass of each element to get the final answer. Use the Periodic table to find the molar mass. Molar mass is located under neath the elements.
One mole of Fe(NO3)3, or iron(III) nitrate, has three moles of nitrate molecules, which have three moles of oxygen atoms each. We can show this mathematically:
1 mole Fe(NO3)3 * (3 moles NO3)/(1 mole Fe(NO3)3) = 3 moles NO3
3 moles NO3 * (3 moles Oxygen)/(1 mole NO3) = 9 moles Oxygen
9 moles of Oxygen in one mole Fe(NO3)3
