Answer:
1. atomic #
2.The sugar-water is a homogeneous mixture
Explanation:
1. However, if it has positive ion, then this electron number will go down (ie +2 charge means two electrons have been lost, so the electron/atomic number will go down by two) and vice versa.
2.Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.

Answer:
a mole of calcium is 6.02 ×10²³, therefore 2.9 ×10²⁴ will be ~4.82moles,
And since a mole of calcium is 40.1g
4.82 moles will be 4.82 × 40.1
that's =193.28g
