Hey there!
The molar mass of magnesium is 24.305 grams.
The molar mass of an element is the same as the atomic mass of an element, but measured in grams.
It's on the periodic table underneath the element symbol.
Hope this helps!
Answer:
1,6,8
Explanation:
Periodic Table- H=1.C=6,O=8
Hydrogen is H, Carbon is C, Oxygen is O
1 miles = 1609.344 m
1 hour = 60 min x 60 sec = 3600 s
30 miles 1 hr 1609.344 m
_______ x ______ x __________= 13.412m/s
1 hr 3600 s 1 miles
Answer:
Δx ≥ 1.22 *10^-10m
Explanation:
<u>Step 1:</u> Data given
The E. coli bacterial cell has a mass of 1.80 fg ( = 1.80 * 10^-15 grams = 1.80 * 10^-18 kg)
Velocity of v = 8.00 μm/s (= 8.00 * 10^-6 m/s)
Uncertainty in the velocity = 3.00 %
E. coli bacterial cells are around 1 μm = 10^−6 m in length
<u>Step 2:</u> Calculate uncertainty in velocity
Δv = 0.03 * 8*10^-6 m/s =2.4 * 10^-7 m/s
<u>Step 3:</u> Calculate the uncertainty of the position of the bacterium
According to Heisenberg uncertainty principle,
Δx *Δp ≥ h/4π
Δx *mΔv ≥ h/4π
with Δx = TO BE DETERMINED
with m = 1.8 *10^-18 kg
with Δv = 2.4*10^-7
with h = constant of planck = 6.626 *10^-34
Δx ≥ 6.626*10^-34 / (4π*(1.8*10^-18)(2.4*10^-7))
Δx ≥ 1.22 *10^-10m
