Answer:
Explanation:
<u>1) Data:</u>
a) M = ?
b) mass of solue = 17 g
c) solute: NH₃
d) V = 0.5o liter
<u>2) Formulae:</u>
a) number of moles, n = mass in grams / molar mass
b) M = n / V (in liters)
<u>3) Solution</u>
a) Molar mass of NH₃ = 17.03 g/mol
b) n = mass in grams / molar mass = 17 g / 17.03 g/mol = 0.998 mol NH₃
c) M = n / V (in liters) = 0.998 mol / 0.50 liter = 1.996 M
d) Round to the appropiate number of significant figures, 2: 2.0 M.
Answer: 2.0 M
The number of waves passing in a certain amount of time
Answer:
You weight would be doubled because gravitational force is doubled
2. Challenges:
a. Everyone’s body would have to adjust to the new weight and learn to walk again
b. Earth would be closer to the sun, so everything would be hotter on Earth
c. Flying airplanes and driving cars might no longer work at all (talk about how difficult this would make traveling)
3. Benefits:
a. Time would go by much slower so technically everyone would live longer
b. Balloons wouldn’t fly off anymore
4. You have to decide for yourself if you’d like it better or worse
