Answer:
One
Explanation:
Trailing zeros in a number are not significant unless they follow a decimal point.
If you want to specify a different number of significant figures, you can use a decimal point.
For example,
2.0 × 10³ = two significant figures
2.00 × 10³ = three significant figures
2.000 × 10³ = four significant figure
2000. = four significant figures
The
functional group found in an ester is a carbonyl group with an attached second oxygen
atom that is bonded to a carbonyl carbon substituent by a single bond, usually
a pair of alkyl or aromatic groups. In addition, it can be shown in
text as RCOOR or occasionally as ROCOR, which made them responsible in the <span>distinctive and attractive
odors and flavors of many flowers, perfumes, and ripe fruits. </span>
According to Henry's law:
C = K P when,
C is the solubility of a gas at a constant temperature in a particular solvent.
K is the Henry law constant
p is the pressure of the gas
we have the pressure and the solubility so we will get the K at first:
by substitution:
0.153 = K * 0.37atm
K= 0.4
∴ C when P = 2.4 atm
∴ C = 0.37 * 2.4 atm = 0.888 = 88.8 g/100g H2O
