Answer:
I will need six (6) bags of potting soil
Explanation:
Since you plan on planting in 10 pots and need 15 cups of potting soil per pot, the total amount of potting soil you need <em>(in cups)</em> is 10 X 15 = 150 cups of potting soil.
We have that a bag contains 25 sups. to get the number of bags needed, we have to divide 150 by 25. This will give us 150 / 25 = 6 bags.
Therefore, I will need six (6) bags of potting soil

Answer: Option (a) is correct.
Explanation:
Molecules of sugar given = 
According to Avogadro's number it is known that 1 mole contains 
.
Therefore, calculate the moles of sugar present in the sample as follows.
Number of moles = 
= 0.25 mol
Thus, the moles of sugar present in the sample is 0.25 mol.
Explanation:
The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)
The relationship between both units is given as;
1 Km = 6.68459e-9 Au
Kulper belt
6.5 billion km = 6.5e9 Km
1 Km = 6.68459e-9 Au
6.5e9 Km = x
Solving for x;
x = 43.45 Au
Alpha Centauri
44 trillion km = 4.4e13
1 Km = 6.68459e-9 Au
4.4e13 km = x
Solving for x;
x = 294121.83 Au
