<span>1 meter = 100 cm
so 1cm is 1/100 *100 = 1% error.
1 kilogram = 1000g
so 1g is 1/1000 * 100 = 0.1% error.
as 1%>0.1%, the 1cm in a meter is the greater error</span><span>

Answer:
25 atm or 190mmHg
Explanation:
Since Temperature is constant we dont need to worry about it so.
P1V1=P2V2
Rewritten as (P1xV1)/V2 Always use liters in gas laws
I Prefer atm so ill convert to that to use in the equation.
(.5atmx.4L)/.8L =.25 atm or 190mmHg
(You can convert mmHg to atm by dividing by 760)
Answer:
Atomic emission spectra are produced when excited electrons return to the ground state. The emitted light of electrons corresponds to energies of the specific electrons.

It is added because NH3 is added
Answer:
added water = 171 ml
Explanation:
Assuming volumes are additive, the rule that we will use to solve this question is:
M1V1 = M2V2
where:
M1 is the initial concentration = 0.4 m
V1 is the initial volume = 57 ml
M2 is the final concentration = 0.1 m
V2 is the final volume that we want to calculate
Substitute with the given in the above equation to get V2 as follows:
M1V1 = M2V2
(0.4)(57) = (0.1)V2
22.8 = 0.1V2
V2 = 228 ml
Now, the final volume is equal to the initial volume plus the amount of added water. So, to get the amount of added water, we will subtract the initial volume from the final volume as follows:
V2 = V1 + added water
228 = 57 + added water
added water = 228 - 57 = 171 ml
Hope this helps :)
