Can someone answer these few questions ?
1.27*10^15 atoms si to mol si
8.65*10^25 molecules ccl4 to mol ccl4
5.80 mol ca to atoms ca

2.10x10⁻⁹ moles of Si, 143.7 moles of CCl₄, 3.49x10²⁴ atoms

Explanation:

These is the relation:

NA (6.02x10²³) ⇒ 1 mol of particles (it can be, atoms or molecules)

This are the rule of three:

NA of atoms occupies 1 mol of Si

1.27x10¹⁵ atoms will occupy (1.27x10¹⁵  .1 ) / NA = 2.10x10⁻⁹ moles of Si

NA of molecules are contained in 1 mol of CCl₄

8.65x10²⁵ molecules are contained in (8.65x10²⁵  .1)/ NA = 143.7 moles

1 mol of Ca has NA atoms

5.80 moles of Ca will have (5.80 . NA) = 3.49x10²⁴

h let me think

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet
