Answer:
Today, the vast majority of us multitask while using our smartphones. We play games, email, surf social media, text, and use apps and other functions while watching television, eating, doing work, or while "engaged" in a conversation with another person. Multitasking has become such a regular part of our lives that most of us believe we do it well—and few imagine it could actually be dangerous.
Explanation:
1. Multitasking is associated with harm to our brains.
2. Multitasking can lead to memory problems.
3. Multitasking can lead to increased distractibility.
4. Multitasking can make us walk into traffic.
5. Multitasking hurts your grades and the grades of those around you.
6. Multitasking can lead to falling and breaking bones.
7. Multitasking can harm your relationship.
8. Multitasking increases chronic stress.
9. Multitasking increases depression and social anxiety.
10. Multitasking makes you less productive and less efficient.

Answer:
Explanation:
First, we need to find the molecular mass of water (H₂O).
H₂O has:
- 2 Hydrogen atoms (subscript of 2)
- 1 Oxygen atom (implied subscript of 1)
Use the Periodic Table to find the mass of hydrogen and oxygen. Then, multiply by the number of atoms of the element.
- Hydrogen: 1.0079 g/mol
- Oxygen: 15.9994 g/mol
There are 2 hydrogen atoms, so multiply the mass by 2.
- 2 Hydrogen: (1.0079 g/mol)(2)= 2.0158 g/mol
Now, find the mass of H₂O. Add the mass of 2 hydrogen atoms and 1 oxygen atom.
- 2.0158 g/mol + 15.9994 g/mol = 18.0152 g/mol
Next, find the amount of moles using the molecular mass we just calculated. Set up a ratio.
Multiply. The grams of H₂O will cancel out.
The original measurement given had two significant figures (3,2). We must round to have 2 significant figures. All the zeroes before the 1 are not significant. So, round to the ten thousandth.
The 7 in the hundred thousandth place tells us to round up.
There are about <u>0.0018 moles in 0.032 grams.</u>
Mass is the property of a physical body and the resistance to acceleration when a net force is applied on the body.
The atomic mass of sodium (Na) is = 22.98
The atomic mass of nitrate (N) is = 14.00
The atomic mass of oxygen (O) is = 15.99
The sodium nitrate (NaNO3) consists of the atomic masses of Na+N+(O)3 = 85 grams
Therefore, the mass of 6.5 mol of sodium nitrate is = 6.5 * 1 mol of NaNO3
= 6.5 * (85)
= 552.50 grams
