Answer:
Well rewriting literal equations can help you understand better and you'll have more room to write the answer and figure it out.
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
The center of the circle is at the origin and its radius is √16 = 4.
So set a compass to 4 and draw a circle with the compass point at the origin.
Answer:
1.5 or 1 1/2
Step-by-step explanation:
Answer:
Amount of NaCl = 23.376 gram
Step-by-step explanation:
Given:
Molarity = 4M
Volume of solution = 100 ml
Find:
Amount of NaCl
Computation:
Molar mass of Na = 22.99 g/mole
Molar mass of Cl = 35.45 g/mole
Molar mass of NaCl = 22.99 + 35.45
Molar mass of NaCl = 58.44 g/mole
Molarity = [moles of solute / volume of solute(ml)]1,000
4 = [moles of solute / 100]1000
Moles of solute = 0.4
moles of solute = Mass of solute / molar mass
0.4 = Amount of NaCl / 58.44
Amount of NaCl = 23.376 gram
Answer:
12 total possible outcomes
Step-by-step explanation:
Because these are independent events, or events that don't rely on each other, the key is to find the possibilites then multiply them all. There are four equal size sections, and three other equal sized sections, so we do 3 * 4 = 12.
