Answer:
1 mole is equal to 1 moles Potassium, or 39.0983 grams.
39.0983g X 4 = 156.3932
so 4 moles are in 156 grams of Potassium

Answer:
it identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional group
Explanation:
It turns from turquoise to yellow or orange when it reacts with reducing sugars.
The temperature in K is 767.4 K
<u><em> calculation</em></u>
This is calculated using the ideal gas equation
that is PV =nRT
where;
P(pressure)= 28 atm
V(volume) = 0.045 L
n(number of moles)= 0.020 moles
R( gas constant) =0.0821 L.atm/mol.K
T(temperature)= ? K\
make T the subject of the formula by diving both side of equation by nR
T =PV/nR
T ={ (28 atm x 0.045 L) /( 0.020 mol x 0.0821 L.atm/mol.K)} =767.4 K
