A scientist needs to check several parameters before coming
to a conclusion about the amount of water pollution. The scientists needs to
check the amount of dissolved oxygen in the water, temperature of the water,
the clarity of the water, the PH level of the water and also the amount of
bacteria present in the water. There may be other criteria’s, but the mentioned
ones are enough to gauge the amount of pollution in the water. Scientists often
takes fish and aquatic plants from the water to be tested to check the amount
of pollution indirectly affecting these species.

No
Explanation: There are 0.0001
Answer is: mass of methanol is 528.32 grams.
N(CH₃OH) = 9.93·10²⁴; number of methanol molecules.
n(CH₃OH) = N(CH₃OH) ÷ Na (Avogadro constant).
n(CH₃OH) = 9.93·10²⁴ ÷ 6.022·10²³ 1/mol.
n(CH₃OH) = 16.49 mol; amount of substance.
m(CH₃OH) = n(CH₃OH) · M(CH₃OH).
m(CH₃OH) = 16.49 mol · 32.04 g/mol.
m(CH₃OH) = 528.32 g.
Hey there!:
a )
number of moles of solute :
moles of solute = molarity x volume ( L )
moles of solute = 1.556 x 200.0
moles of solute = 311.2 moles of KBr
____________________________________________
b) Molar mass of KBr : 119.002 g/mol
1 mole KBr ----------------- 119.002 g
311.2 moles ---------------------- ( mass KBr ) ?
mass glucose = 311.2 x 119.002 / 1
mass glucose => 37033.4224 g
