Answer:
I think so henterogeneous
S + O = SO4. cracked also chemical reaction
M.P of oleic acid = 13 deg C
<span>B.Pof oleic acid = 360 deg C </span>
<span>(360 - 13) / 100 = 3.47 </span>
<span>So 1 deg O = 3.47 deg C </span>
<span>The scale do not start at 0 deg C, it starts at 13 deg C. So to convert deg C to deg O,
subtract 13 then divide by 3.47 </span>
<span>deg O = (deg C - 13) / 3.47 </span>
<span>convert O to C multiply by 3.47 then add 13 </span>
<span>deg C = (deg O x 3.47) + 13 </span>
<span>convert 0 deg C to deg O </span>
<span>deg O = (0 deg C - 13) / 3.47 </span>
<span>= - 3.75 deg O</span>
Answer:
4.5 g
Explanation:
Given,
Moles of water = 0.25 moles
Molar mass of water (
) = 
= 18 g/mol
The formula for the calculation of moles is shown below:
Thus,
<u>Mass of water in 0.25 moles = 4.5 g</u>
