Math that what my friend says math!!!
Avogadro Number of molecules is contained in 1 mole of water
6.02 * 10²³ molecules are contained in 1 mole of water.
2 * 10²² molecules will contain: (1* 2 * 10²²) / (<span>6.02 * 10²³)
</span>
≈ 0.0332 mole of Water.
--> 0.058 g NaCl = 100 g solution
<span>1 g = 100/0.058 g solution </span>
<span>1.5 g = 150/0.058 g = 2586 g solution </span>
The objects that are rubbed together will create charges among themselves due to friction.
(1) The balloon rubbed with a wool cloth will be charged.
(2) If she comb near a small, uncharged object nothing will change.
(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
