Home safety is always very important, but it becomes a particular concern when a child enters a home. This type of safety includes many different considerations--you want to protect family members from deadly falls, fatal fires, hazardous ingestions, and more. Practicing safety at home is also an important consideration if you have elderly people in your home. It's even important if you have pets in your home. You have to be diligent to keep all dangerous items in your home out of the reach of people or animals it can harm. To maximize home accident prevention, make sure all child-safety locks are secure, all smoke and carbon monoxide detectors have fresh batteries, and numbers for emergency services and personnel and prominently and clearly displayed.
Answer:
0.087 moles of water
Explanation:
Given data:
Number of molecules of water = 5.24×10²² molecules
Number of moles of water = ?
Solution:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules of water
5.24×10²² molecules × 1 mol / 6.022 × 10²³ molecules
0.87×10⁻¹ mol
0.087 mol
