Answer: Hence, the mass of each ice cube is 5 grams.
Explanation:
Mass of water in Glass : 30 grams
Rooms available for ice cubes in a tray: 6
Joanna carefully pours out the water from the glass into ice tray without spilling the any water, so, the mass of the water in glass will get equally divided into 6 rooms.
Mass of the water in one cube =
Hence, the mass of each ice cube is 5 grams.

This is what I got hope this makes sense:There is 1 mol of Mg 2+ ions in one mole of MgCl2, we can get that from the formula.
Multiply 3.00 moles by 6.022x10^23 to get moles of MgCl2.
There are 6.022x10^23 ions in one mole of substance.
(3.00)(6.022x10^23)
=1.81x10^24 Mg 2+ ions
Hope it helps though
