mass of proton mp=1.672621898e-27 kg and 1 amu=1.66053904e-27kg so it’s just divition (1.672621898e-27 / 1.66053904e-27) =1.007276 amu
Answer:
0.33%
Explanation:
From the question given above, the following data were obtained:
Experimental value = 9.842 m/s²
Accepted value = 9.81 m/s²
Percentage error =?
The percentage error in the calculation can be obtained as follow:
Percentage error = |Experimental – Accepted| / Accepted value × 100
Percentage error = |9.842 – 9.81| / 9.81 × 100
Percentage error = 0.032 / 9.81 × 100
Percentage error = 0.33%
Therefore, the error in the calculation is 0.33%
Waterways or lakes. at least that’s what google said lol.
We see that the molar ratio of sulfur to water is:
3 : 2
We first compute the moles of water:
moles = mass / Mr
moles = 37.4 / 18
moles = 2.08
By the ratio, moles of sulfur:
3.12
Mr sulfur = 64
mass = 3.12 x 64
mass = 199.7 grams
Answer:
aluminium is more reactive than carbon. carbon is used to displace less reactive metals from their compounds. this happens since the carbon reacts with the other substance(s) in the compound, and the less reactive metal does not.
