Answer:
Kilograms
Explanation:
The metric system denotes their measurements with prefixes (kilo)
10.861% / 100 = 0.10861
12.428 % / 100 = 0.12428
(0.10861 * 187.9122) + (0.12428 * 190.9407) <span>+ (0.76711 x 192.8938)</span>
= 192.1100 amu .

Answer:
0.001 M OH-
Explanation:
[OH-] = 10^-pOH, so
pOH + pH = 14 and 14 - pH = pOH
14 - 11 = 3
[OH⁻] = 10⁻³ ; [OH-] = 0.001 M OH-
When the cool and hot zones of a non luminous flame’s air
control valve is closed, the gas in which will be in placed as first and as it
encounters air as it was in the mouth of the burner, there will be a presence
of incomplete mixing, causing a combustion which would be incomplete and will
also lead to a process that can’t be controlled, resulting to flame that is
cool.
Atomic mass Carbon (C ) = 12.01 a.m.u
12.01 g ---------- 6.02x10²³ atoms
1.50 g ----------- ??
1.50 x ( 6.02x10²³ ) / 12.01 =
7.51x10²² atoms of C
