Answer:
2.56
Step-by-step explanation:
8* 32=256
256/100=2.56
Answer:
434822.11875961m
Step-by-step explanation:
this is because the formula is λ = C/f
Where,
λ (Lambda) = Wavelength in meters
c = Speed of Light (299,792,458 m/s)
f = Frequency
One-half a number (x) is equal to 14.
One-half: 1/2
a number x: multiplied by x
is equal to: =
1/2x = 14
If you were going to solve for it, divide both sides by 1/2.
x = 28
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
