Answer:
The molar mass is: 18.02 g/mol.
Explanation:
- Mass of two moles of Hydrogen atoms (H2) = 2x 1 g/mol = 2 g/mol.
- Mass of one mole of water (H2O) = 2 g/mol + 16 g/mol = 18 g/mol.
1 mole of Hydrogen= 1.01, so if we have 2 moles of it here, that would be 2.02.
1 mole of Oxygen (that's all we have here)= 16.00
Once you add the two together (2.02+16.00), you will get 18.02.
I hope this made sense! Have a great day!
Answer:
2-carbohydrate
Explanation:
Sucrose belongs to the carbohydrate family. It is a disaccharide which is derived from the condensation of glucose and fructose.
- In the body, they are sources of energy for living processes.
- Upon hydrolysis such disaccharide produces tow monosaccharide units.
- Food substances that are energy rich will contain some of these organic molecules.
Iron, but there are some amounts of other dense elements like gold, platinum, and uranium.
Answer:
yes
Explanation:
it wont dissolve because when water is cold its molecules dont separate
The molarity of the acetic acid solution is calculated as below
calculate the moles of KOH used
moles =molarity x volume
= 20.9 x0.267 = 5.58 moles
write the reaction equation
KOH + CH3COOH = CH3COOK + H2O
since the reacting ratio between KOH to CH3COOH is 1:1 the moles of CH3COOH is also = 5.58 moles
molarity of CH3COOH = moles/volume
=5.58 /29.1 =0.192 M
