?When a problem says "...identify the unknown element..." I think: that can be done using the??

Answer the questions below using the available keywords as answers: concentration moles volume atomic mass mass number molar mass formula mass atomic number molarity = moles/liter moles = grams/formula mass When a problem says "...15 g of water..." I think with that information I can find moles e molar mass When a problem says "...what volume..." I think, to find volume I need moles When a problem says "...what is the concentration..." I picture the equation molarity = moles/lit When a problem says "...identify the unknown element..." I think: that can be done using thi/molar mass = grams/mole ^ or atomic mass. When a problem says "...how many ions..." I know I need to find the moles When a problem says "...how many moles are in a solution of..." I think to find moles in a solution I'll need concentration and volume When a problem says "...how many grams are in 1.3 moles of..." I picture the equation moles = grams/formula mass

Explanation / Answer

using the atomic number only we can say the unknown element

i hope rest all are correct
