Answer:
16400g
Explanation:
The amount of Calcium nitrate {Ca(NO3)2} that will be needed can be calculated as follows:
Molarity (M) = number of moles (n) ÷ volume (L)
According to this question, molarity = 0.2M, volume = 500L
number of moles = molarity × volume
number of moles (n) = 0.2 × 500
n = 100moles
Using mole = mass/molar mass
Molar mass of Ca(NO3)2 = 40 + {14 + 16(3)}2
= 40 + (14 + 48)2
= 40 + 62(2)
= 40 + 124
= 164g/mol
Mass = mole × molar mass
mass = 100 × 164
mass = 16400g of Ca(NO3)2
Low fat milk contains dissacharides, thus it will provides short term energy more than long time energy. due to its lack of fat. Whole milk contains both fat and sugar, thus it is more suitable for production of long term energy. The quantity of fat in these two milk is the big difference between them.
Rise and fall.
if a bullet is aimed at a target facing East,100 yards away,it will impact 1" high.
turn around and aim at a target 100yards to the west and it will impact 1"low.
the effect is the gravitational pull of the bullet traveling the same direction of the planets rotation
