3) The factors that can affect climate of an area, by latitude and longitude!

Answer:
46 g
Explanation:
First we <u>convert 1.2 x 10²⁴ atoms of sodium into moles</u>, using <em>Avogadro's number</em>:
- 1.2x10²⁴ atoms ÷ 6.023x10²³ atoms/mol = 2.0 mol
Then we <u>convert 2.0 moles of sodium into grams</u>, using <em>sodium's molar mass</em>:
- 2.0 mol Na * 23 g/mol = 46 g
Thus, there are 46 grams in 1.2x10²⁴ atoms of sodium.
<span>64.94
First, write out an expression about what we know
0.6915 * 62.93 + 0.3085 * x = 63.55
Now solve for x
0.6915 * 62.93 + 0.3085 * x = 63.55
43.5161 + 0.3085 * x = 63.55
0.3085 * x = 20.03391
x = 64.93972
Rounding the answer to 2 decimal places gives x = 64.94</span>
